Your suggestions about render-speed-optimated PCs

Hi everybody

I'm thinking about a new Render-machine for DAZ Studio.
Several setups/possibilities are on my list... wich one is the most useful?

- used workstation with 16GB+ and dual Xeon / average (?) graphic (nVidia Quadro)
- random system with SLI / crossfire
- custom prosumer-system with i5 or ati-cpu, (fast) single graphic and a bunch of RAM

At the render settings I can check, what GPU-devices should support rendering, right?
Is SLI / crossfire useful then? ... beside a fast rendering in preview-mode?

Greetings,
Daniel

SLI is not used by Iray (but with it disabled the nVidia cards may be, if they are recent enough), Crossfire is AMD and those cards are not used by Iray at all. For iray ou want the best nVidia GPU(s) you can get, bearing in mind that we don't know when the 10x0 cards will be supported - best being most memory, most CUDA cores. If you mainly use 3delight, or if you do very complex scenes that will overwhelm even a high-memory GPU, then you want the fastest CPU/most RAM you can afford.

A question along this line.

I have an i7-5820K Intel CPU, 16GB DDR4 RAM and 2 EVGA GTX 970 4GB video cards.  Not set up in SLI

I plan to move up to 10x0 card(s) when Iray supports them, want more Video RAM and CUDA cores.

Question is will moving to 32 GB RAM help now or in the future or both? 

Thanks.

More Ram always helps :)

If your scene exceeds the 4GB of your video card, Iray won't use the card anyway.

the more system ram you have, the bigger the scenes you can create and the more stuff you can cram into your scene before Daz starts to lag

Thanks, may look at adding 16GB more, I have the slots
