I'm not a enthusiast gamer, but I do play some COD4 and FO3 so having a nice GPU setup is a must. Be that as it may, I would also like to run this new CUDA deal and from what I gather, the power in the GPU for CUDA comes from the stream processors. Now of course all things are not equal, but as I upgrade I should look for cards with a high stream processor count to help move things along. Any other help will be appreciated.

Another question, will SLI scale as typical ~10% or will a second card double the performance?

I read in a computer magazine that adding a second video card in SLI mode will not double the performance. You would get about 20-30 percent improvement. With two same GeForce video cards in SLI mode, you would get one cuda credit. If you disable the SLI then you will get two cuda credits.

No longer true with the newer 190.xx and later drivers.
