Core I7 6700k 16gb Ddr4 Geforce Gtx 980ti 6gb

 

What would you add? 

What pc you have and how much time it takes you to render complex images with two G3F with background in high detail. Thanks!!

    You'll never be sorry if you add another 16 Gb of memory.

    16GB should be enough for that kind of scene. I have 32GB but I rarely drift above 16GB. However as fastbike1 says, 32GB would give you a better ceiling to avoid hitting occassional memory problems. Once you add in HD, more characters, some sub-D, a complex environment etc, the memory use quickly spirals upwards.

    Why anyone would have a $700 graphics card but not 64GB or more RAM for the CPU is beyond me.

    Could depend on whether you're using Iray or 3delight.  If the former, like me, you'd want to max your CUDA cores, and prioritise the 980ti in your budget over system RAM.  By the time you have exceeded the 6Gb of VRAM, you might have exceeded 16Gb of system RAM, but 32Gb?  I'd guess not.  So unless your rendering a battle scene along the lines of the Lord of the Rings trilogy, in which case you'll have to wait for several centuries while Iray renders on CPU only, I wouldn't see much point in more than 32Gb - would you?

    I have a GTX 980 ti and 32 GB RAM. I have never had a RAM problem with 32 GB. Some people are recommending holding off on buying a graphics card until the Pascal series is released. I guess it depends on how urgent your need for an upgrade is.

    I'm not touching any new HW that isn't DirectX 12 / Vulkan / Metal compliant and since the SW isn't their quite yet for that support I'm waiting. Last go round with expensive HW I bought the 1st round of Intel i5 Intel Graphics HW and not only was support by Intel and ASUS abandoned after 1 1/2 years but the HW burned completely up in 3 years. That hassle and poor value for a $1500 PC? No thanks.

    Thanks to all for the answers. Hi Barbult. How much time it would take you to render a image with two G3F a simple background and simple light? Like the image attached

    *Two G3F with clothes

    *Shaded heaven enviroment used in The barefoot dancer

    * Barefoot dancer lights

    * Barefoot high render settings

     

    Thanks!

    I noticed V4 clothing on G3F with auto-fit and adding SubD & smoothing really upped the memory use.  I started at 16GB, but with two G3F in V4 clothing that got used up.  Since I have upgraded to 32.

    Note that "higher detail" isn't really the quality that varies in this case. A more capable NVidia graphics card will let you render scenes faster. More VRAM in the card will let you render a bigger, more complex scene without falling back to the much slower CPU rendering. But if you compare a scene rendering on a barely-capable system and a high-spec system, the render quality will be identical. Only the render speed will vary.

    Barbult: Yeah, I'm trying to hold off on a machine until I see how Pascal shakes out. I figure that at the very least really hot sh* Pascal machines will make all the previous machines much cheaper.

     

    Granted, I had a recent scare with my machine, so I don't know if I'm going to HAVE that time... but we'll see. ;)

    I would like a pascal GPU aswell, but I normally hold off on brand new tech due to the massive premium you pay as an early adopter. I suspect it could be a year or more before pascal GPU's appear at what we would consider reasonable consumer prices.

    Yeah I think Pascal based GPUs are still a ways away.  Can't really complain though, I have quite a bit of power already.
