1080 Ti: what's best for Iray?

Thinking about impoverishing myself. A little confused about Founders Edition v gaming v extreme. Can anyone offer a simple and clear way through the terminology for rendering (not a gamer)?

    I can only offer a little on this...

    Founder's Edition is the original "reference" design for the card. And if you look at the FE cards, often (always?) they are enclosed with maybe only a single fan. I think the other card vendors take that reference and modify it for their target customers. So they'll add tons of fans and other stuff.

    The enclosed design with a single fan is designed for worst case, small cases, to ensure the card has the best cooling in the tightest spaces. Other cards with multiple fans assume the user is a heavy gamer who will overclock and put the card in a big case with lots of cooling. 

    So I guess it comes down to how you'll apply the card. Overclocking in a big case with lots of cooling? Or just standard use in a small case? Or maybe in-between?

    One advantage of a card with multiple fans is lower noise. Since three fans should be able to achieve the same level of cooling as a single fan by rotating significantly slower, then the overall noise is less, despite the fact that you have more fans on the card.

    I guess if the GPU's are putting out the same heat, then 3 slow fans cool the same as one fan. But if the 3-fan GPU is overclocked and hot (which is why you'd want the 3 fans), wouldn't the 3 fans be operating at higher speed and therefore louder?

    How loud is the sound of your GPU melting?

    Not sure I understand your point. He said a benefit of multiple fans is quieter. I asked if that's the case when the GPU is cranking at max power and overclocked.

    A 3-fan card may be really noisy under those conditions, but a single-fan might be insufficient, so if you're going to be pushing the card that hard, better 3 noisy fans than the card overheating.

    Indeed, however much the GPU is overclocked 3 fans will always need to spin slower than a single fan in order to achieve the same cooling effect, and naturally if the fans are cranked to full speed then 3 fans will naturally cool a lot better than 1 fan at the same speed.

    I think it depends on your case. 

    Founder's edition cards have a single fan, but the airflow is directed past fins and blown out the back of your case.

    Other cards have multiple fans, but that won't do you much good (or have to run very fast) if you have a case with limited airflow.  If not enough air is moving through the case, you'll just have hot air recirculating through it.

    Another option:  I just got water cooled, and quite impressed with it.

    Yeah, I know I'm late to that party.  What made me leap to watercooling now is the all-in-one solutions warrantied by the manufacturer.  I got the EVGA Hybrid cards.  1080 Ti SC2.  Running at over 1900 MHz clock rendering at 50C or less, after only installing default EVGA stuff.

    Good point about cooling fans.  I've seen many people just stick cooling fans in the case and thinking that will solve the problem, when in fact often they are making the problem worse!  Cooling needs an intake source of cool air and an equal size port to exhaust the heat.  And then there is the direction of the airflow to consider.  If you don't have the right balance, you can turn your PC Case into an oven.  Watercooling simplifies the cooling process to some extent.  The cooling design is simpler.  I advise against trying to add more fans to your existing case unless you know what your are doing.

    Geez...nobody look at GTX 1080ti prices at Newegg unless you want to get real depressed. Today they're between $800 and $1,000. Sickening.

    I'm seeing this one for $759 which is $20 less than MSRP: https://www.newegg.com/Product/Product.aspx?Item=N82E16814487338&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Video+Card+-+Nvidia-_-N82E16814487338&gclid=CN6koODFidUCFd64wAod-sUF3g&gclsrc=aw.ds

    What is really disciuraging is rhat the GTX 1070 prices which used to be $300 - $400 are now in the $500 to $700 range: .https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=GTX+1070&N=-1&isNodeId=1

    That is what caused me to spring for the GTX 1080 ti. More card for not much more money.
