Default Re: CUDA Question.

It won't work with SLi, but you can just use a board that has two PCI-e Slots.. then fold with them without needing SLi..

That's how the 4 9800GX2's were done on that 790FX Board

ATI cards have more shaders, but the Nvidia shaders run faster which is why they fold faster.

The new projects change things a little bit, but Nvidia cards till come out in the lead.
