    Your parts list will build a solid computer that will work well for the foreseeable future.  Especially since you are not a computer geek and probably won't want to upgrade the box yourself.  There is nothing wasteful or excessive there.  Those parts should keep you happy for a long time (except for HD space, which we can never get enough of). And your games will fly.

    Again, I think it's important to see how much they're charging you for that parts list. I wouldn't recommend it if they're charging you $4,000 USD smiley

    Also, since I recall "frio" is Spanish for cold (or something like that) I assume the Corsair "enfriamiento liquido" is a liquid cooler? I also assume you're paying a significant amount for that, and those are typically designed for overclockers. Since the Ryzen 7 1800x is just a more expensive 1700 with a higher base clock, you might want to consider saving some money and going with a Ryzen 7 1700 with the included air cooler if you're not going to be overclocking. 

    Also, the 240GB SSD might not be enough for your needs. Typically you'd put your operating system and applications on the SSD to get fast response on loading, so you might want to check how much you'd need to fit all your stuff. I have a 500GB SSD and already I'm using almost 250GB. It may be fine, I'm just cautioning you to make sure before you buy.  

    EDIT: Yeah, I just checked Newegg and it's a liquid cooler which costs over $100. If you can use a 1700 with included cooler you might be saving a couple hundred $$.

    Thank you very, very much for all the info!

    To add more details on my needs:

    My top priority is to render as fast as possible in DAZ Studio with Iray. Imagine having to render a big quantity of images in a deadline. Doing a big series of promo images... not just occasional renders. That`s it.

    On second place, I`d like to be able to handle big 3D projects if needed (modeling, rigging in ZBrush and DAZ Studio). For instance, I did a fiber mesh hair, the hair load fine in the scene, but the weight map brush is not responding due to the heavy poly count.

    On a faaaaar away third place, I`d say gaming, but this is 0 priority. I wouldn`t spend anything extra on that alone.

    My iMac will continue to be my main machine, I just love it and can work fine with it most of the time. This other one would be for the heavy duty tasks described.

    So, while I don`t want to spend more than needed, this is an investment, and not a luxury. I am willing to spend a bit extra IF it is worth it, but without going crazy! This is the premade PC I showed in the original post with changes. I can`t do big changes to the original setup in order to mantein the "combo" price. But here is the quote they gave me, all opinions are welcome. :)

     

    This looks like a very solid build, though there are two things that I would change.
    I would get a Western Digital Black Edition instead of that Toshiba.
    I would swap out the 2.5" SSD for a M.2 NVMe SSD card (should ba around the same price and will be a lot faster)

    Also, maybe some of the overclockers can respond, but I think that liquid coolers might need regular maintenance? Like replacing the cooling liquid? Maybe not on this one, but if you might want to check to see if the liquid cooler will include some hassle you don't really want. Personally, I tend to steer clear of them because they're not really needed for my computers, and I worry too much about liquid leaks and stuff.

    With the H100i, (an All in one closed loop) no, no maintenance required.  The only thing that will go eventually will be the pump.  But then you just swap it all out.

    Custom loops, yea, you need to check water levels etc.. but the benefits far outweigh issues like maintenance (for me personally, that is).

    this liquid cooling is a top notch product.  there is no maintenance, no spills, just cheap cool insurance..  He probably could save money going to a lower model (100i is the top shelf), but not much and probably not possible for him anyways.  If he had one for his gpu too, that would be even better.

  • TangoAlphaTangoAlpha Posts: 4,587

    The H100i v2 (Corsair Hydro Series) is a sealed unit water cooler. They're pretty much maintenance-free. I've had one on my rig (i7 6700K) for well over a year and it's performed brilliantly.

    Thank you all!

    The total cost would be aprox. US$2400. Hurts my wallet, but not many options here in Costa Rica LOL.

    The thing with the cooling and the Ryzen seems like a good way to save some extra money, I don’t even plan to overclock anything. :P

    The good thing about the cooler is that  it is a great way to protect your investment.  Even if you don't plan to overclock, you can be sure that you cpu will be nice and cool even when it is working hard.  When your computer is your bread and butter, there is nothing like cheap insurance.  Too bad they didn't include one for your 1080ti.   By the way, your hair products are great.  Keep up the good work.

    I added prices up from around the net (mostly Newegg) and it's not bad.  About $2000 USD without the RAM, since 8GB is listed but you said 32GB.  Actually, if 32GB their price is very good, you would spend about the same building yourself.

     

    Agree with JamesJAB, upgrade to an M.2 drive.  At that capacity, there will probably be a very minor difference in price (like $20, you want one with NVMe interface).

    I dunno it just seems kinda strange to spend a few hundred extra $$ for a high end CPU with high end liquid cooler when theres no indication the apps youre running make much high end use of the CPU. And even if youre slamming your CPU with constant renders (which most of us arent?) isnt it designed to operate for its lifetime at base clock frequency with stock cooler? Why not take that money and use it on other components?

    Maybe the reason you think its strange is because you are not a 3D professional?  Yes, thats why.  Zbrush users don't seem to think its strange.  There are threads about this very topic in the Zbrush forum. Guess which is the most popular choice for cpu's?  Did you notice that the OP uses Zbrush and does other "heavy duty" 3d work?  You think its strange to buy a fast processor for heavy 3d work? Because heavy duty 3d work doesn't greatly benefit from a fast processor....so he should buy a slower processor so he can make less money per hourfrown?  Thats strange.  The Ryzen is not a workstation processor but it delivers the performance of an entry level workstation at half the price.  Every 3d professional can work better with a decent performing workstation.  At that price, there is nothing more sensible for professional on a budget.

    Good point, although it's not terribly high-end.  It's high end on the consumer level or for office type apps but there's much more powerful CPUs for professional use.

    Before getting into 3D rendering, I considered it a good mid-range sweet spot.  About $300 or so got you a nice CPU that would last a while before feeling like it got slow, but not so expensive you felt bad upgrading in about 3 years. 

     

    Anyhoo, a number of reasons/thoughts on builds.

    1. The watercooling without overclocking - purely aesthetic.  Keeps the CPU cool for heavy workloads and max boost frequency but the inside isn't cluttered with a monstrous air cooler.

    2. The watercooling without overclocking - for CPU longetivity.  Eh here IMO, as long as you're running in reasonable ambient temps the system is designed to run on a stock cooler and last many years.  Also water adds some risk.

    3. Watercooling with moderate overclocking.  Self-explanatory, water cooling will get you farther than air.

    4. Watercooling with Xtreme(!) overclocking.  See #3.

     

    1800 does make sense if he won't overclock and just wants the higher frequency processor.  Or, purely from the point of another $100 is less than 5% of the overall cost to get the fastest CPU for that platform.  Otherwise, with the watercooler could save $100 going to a 1700 and overclocking it.  Or, if purely need to knock the price down at stock speeds the 1700 will be such little difference rendering in Studio with Iray it probably won't make a perceptable difference.  The higher freq. could benefit gaming, the games which rely on single core speed.

    Again I'm talking about the Ryzen 1800x liquid cooled vs the 1700 with stock air cooling. Cost difference maybe $300, and benefit to non-overclockers of less than 15% improvement in CPU clock speed. If thats important with ZBrush, tben absolutely get the 1800x.

    Don't forget he does some gaming too, as mentioned many don't multithread well and performance depends on single core speed.

    I have to disagree with you on this point.  Consumer grade cpu's (which Ryzen is) are designed to operate within parameters with a stock cooler for average cpu loads.  Gamers use their computers for hours at a time but rarely is the cpu running at full duty on all threads.  But if you are stressing all threads, there is a bigger chance (slight) of overheating or at least of running higher than normal temps.  This can affect longevity especially when it is grouped with a high end videocard or two in the same box.   Workstation class cpu's combat this problem by underclocking (Xeon's are considerably underclocked from their i7 brothers), special engineered case cooling, and heavy duty stock coolers.  Watercooling is a very cheap insurance to avoid any possible calamity.  I agree that it's probably not necessary, but if you depend on your computer for a living, it will certainly help you sleep well at night.

    Another thing to keep in mind, he mentioned being in Costa Rica (tropical climate?)  If the house/appartment is relying on open windows or a swampcooler (water cooled air), the liquid cooling will be a very good option for keeping the CPU cool in a less than optimal ambient temperature.
    If this is the case, I would highly recomment seeing about paying the extra for the hibrid cooling version of the GTX 1080 ti.  (These cards liquid cool the GPU core and air cool the VRAM)

    Corsair makes a nice hybrid 1080ti.  That would go perfectly with his system.

    If it adds piece of mind, it's relatively cheap.  JamesJAB makes a good point, if he's running in a tropical environment without AC.

    I've never killed a CPU, and we even abused them a bit.  The consumer grade ones.  At one job, we had our PC's running Prime and other shared computing apps that hammered the CPU, ran in the off business hours on stock coolers.  Not only have I never killed a CPU personally, I never saw one die at work (in IT).  I had overclocked CPU's running for many years too.  I'm not saying it's impossible, but IMO very improbable.

    I have never killed a CPU either and i usually buy second hand.  But I have seen it and I have heard of it.   If the extra cost was high, I might recommend he forgo it, but just $100?  Yeah, improbable but suffering loss from a natural disaster is also improbable and if someone offered me cheap protection, I would probably take it.

     

    edit... there is also another potential benefit.  It will lengthen the duty life of his cpu.  I mean, one thing is for sure, technology will not stand still.  Future apps will demand more and more from the processor.  This way, he always has the option of overclocking and adding more usefulness to an old cpu in the future.

    Im sure we can all come up with a list of stuff that might sound reasonable, but its the facts and numbers that matter. Yeah living in the tropics might sound like a reason for extra cooling, but in practice that probably doesnt account for much practical difference. Most of us dont keep our rooms much over 85F or 30C, and with aircon usually hang around 75F or 25C. So from a CPU perspective is 5C higher ambient during the day that big a deal? Maybe, but thats assuming a lot

    Thats the difference between business use and hobbyist use.  If a business user loses their computer, their lifestyle is at stake so they try to cover all their bases.  If a hobbyists does, they just don't get to play for a while, no problem they can play with something else.  Big difference.  This is why business users will buy a costly UPS (no performance benefit at all) and keep their computers in an air conditioned environment.  Because there is more at stake.  You seem to lack this perspective. $100 dollars to insure a piece of equipment is not a big deal for a professional but it may be a lot for a starving hobbyist.

  • Actually for me, it's the noise benefits rather than cooling.. if I ran all these rigs on air coolers (both CPU and GPU) it would be unbearble to work in all day.  As they are, all under water, they can run 24/7 and neither heat or noise is an issue.

    A big thing I think you're forgetting is that the water cooling adds risk.  Could spring a leak and kill the whole system, vs. just the CPU going TU.  The water pump could also die and then CPU could die before thermal shutdown.  I don't know if actual numbers are out there, but I my guess is that  there are more cases of water cooling failure vs. a CPU dying from overuse at stock speeds.

     

    Having said all that, I currently have a few water cooled 1080 Tis and my new system is going to be water cooled.  Water cooling does offer great benefits.  smiley

    I wish I had that problem.  I have a workstation for general use and a renderstation, so the noise isn't bad enough yet.  Strangely enough, I enjoy the sound of my Dell working.  It's reassuring.  But I wish I had a few more render stations in my office to bother me.  It's the heat that gets me.  At night when I am rendering full time,  I have to take off my shirt to work and it is still uncomfortable.

    Drzap do you have any facts and numbers to support your point, or just a general belief that all professionals need more, better, and faster?

    Fact:  If you are a professional (any profession), the faster you work, the more benefits to you personally.  If you own the business, you get your money faster.  If you are a worker, you get to finish and go home faster (or maybe your boss will give you more work (that is not a benefitfrown)

    Fact:  Faster processors with more cores will allow you to do more and sometimes better 3D work.  The heavier the 3D work, the more benefit if gives.

    Fact:  3D professionals regularly upgrade their workstations primarily for the two above reasons.  This also benefits me because I can pick up a cheap workstation.

    Would you like any more facts?

    As I suspected your "facts" are more, better, and faster as opposed to an analysis of where best to spend money on a new computer based on cost/benefit (using facts and numbers) and what apps youll be running. For example is it better to spend money on top line CPU and water cooling or more GPUs.

    I think you are a little tone deaf.  Computer advice is specific to a user's needs.  The OP has describes his needs and wants in detail.   His computer choice is almost optimum for what he wants.  In this case, his budget allows for a water cooler and a top GPU.  He stated he didn't want more than one GPU.  Your analysis seems to only apply to your own situation.  The other people offering advice are giving it considering the needs of person asking.
