I'm building a Pr/Ae workstation for a friend. He was going to buy a fully decked out Mac Pro (at least $5000), and I managed to talk him out of it. His main goal is to be able to work with 4k video. I was going to get him a Quadro, but then I started researching and was quickly dissuaded. Long story short, I've decided on getting at least one 780 Ti. What my question is, though, when using Multi-GPU in Pr/Ae CC, would it use the combined CUDA cores and VRAM of 2 cards? If I understand correctly, SLI only uses the GPU of both cards, and not the VRAM, so if it doesn't use SLI and instead uses different Multi-GPU support, would it use both 3gb of VRAM, adding up to 6gb total?
LOL. I'm such a noob at this. Thanks for that, that was really helpful. I just wish pages like that were readily available without scrolling through pages of Google to get to.
GPU acceleration and scaling across multiple cards/GPU's is not the same Tech as SLI nor does it require SLI. Yes scaling across GPUs for GPU acceleration uses the VRAM from both cards because GPU acceleration requires that ability to even work on 2 cards. 2x 780TI cards would be a good investment with 4K media.
