Hey guys -
was just about to pull the trigger on a new $3000 2950x 5 GPU ( 2 RTX 2080 ti's and 3 GTX 970's ) iRay rendering rig to replace an i7 5930k setup (using 2 2080 Ti's I already have ) using a program called DAZ studio. A program that makes use of all GPU's without any SLI connector. I believe the software actually recommends not using SLI because it reduces performance. Current rig has a x99 Deluxe MB with 5 GPU slots but can't use the 970's because of how big the 2080 ti's are. Then I saw that the software does not take advantage of multiple cores. In fact, there's a benchmark thread at a forum where my existing rig using 2 RTX 2080 Ti's OC Gaming was actually a few seconds faster than a rig with an i9 9900k and two 2080 Ti's. I believe his cards were non OC. So now I'm leaning towards maybe just modding my existing system to use the 3 970's by just getting 2 or 3 PCIE risers. Install the 3 970's into the 3 lower slots on the mb and use the risers for the top 2 slots with the 2080 TI's mounted externally. That's like spending 70 bucks for riser cables to convert my rig to add 3 GPU's and maybe another $50 for a PSU if my current 1000W is not enough. The $3k mentioned above will be for a motherboard, 2950x cpu, case, 1300W PSU, 32Gb ddr ram, water cooler, 1Tb SSD.
You guys think this would work? My other concern is if the 40 PCIE lanes will seriously impact rendering performance vs the 64 on the 2950x.
