My 3D rendering program of choice, Keyshot, has recently added support for GPU rendering with Ray Tracing on Nvidia cards. I'm concerned about memory capacity because I can easily fill up 10GB+ with assets and materials when rendering on my CPU. Unfortunately, you can't pool VRAM with Keyshot yet, but apparently that function is in the works. I also game on a 34" 1440p monitor and will be using the GPU to power my Oculus Quest through link.
I'm planning on upgrading to a 2070 SUPER soon, with the intention of adding another 2070S with NVlink when support for pooling VRAM is added, giving me 16GB total. I'm aware that the B450 Tomahawk only has 1 PCIe 3.0 x16, with an additional PCIe 2.0 x16. And the 2700X has 16 lanes for GPUs. I'm struggling to find answers as SLI in gaming becomes less popular.
Am I going to run into problems (PCIe, power handling, bottlenecks etc.) if I add in second card on my B450 Tomahawk with my 2700X?
Thanks
