I'm going to be using 2 gpu's (probably 4070 Supers) and am looking for a board that will bifucate the 16x slots in to 2 8x.
Considering:
ASUS ProArt Z790-CREATOR WIFI $439
ASUS ROG Maximus Z790 Hero $529
ASRock Z790 Taichi $479
Any others...
This is something I've noticed in the past while working, there's a definite performance loss while you're actively working if you are using the same GPU to render with. If you offload the rendering to a dedicated gpu, it's like no performance...
Good question. I'm guessing I don't. The rendering gpu might benefit from the direct cpu connection, but I'd think the other card driving the monitors might be ok on the chipset. Just guessing though.
you would maybe already know, but for some rendering workload you do not need that much bandwith (i.e. there a lot of long compute made on the gpu relative to the interaction with the rest, loading time, a bit like compiling and hard drive...
Since you do GPU rendering, do you need more than 6 or 8 cores for that workload?
If not....the 7900X3D is on sale for $410 at Amazon, Newegg, and B&H. Great price and Would be a fantastic CPU to split the workloads. Games on the V-cache CCD and...
For a 14900K I'd go with Z790 motherboard, they usually have plenty of NVMe (1 from CPU, 2-4 from chipset) so you'd be set for storage.
Unfortunately modern boards aren't very likely to offer dual full-length PCIe slots from the CPU with x8/x8...
Time for an upgrade.
I do 3D work and GPU rendering, so use 1 card to drive the monitors (and gaming) and the other card for rendering.
Current system is an i7-6700K, with 2 gpu's, a GTX 1060 and a GTX 1070.
It has served me well for several...
