Hi Guys:'

I have an Msi Mobo with Crossfire/SLI capability. My power supply is 750 watt . Currenlty this sandy bridge (i25ook) is oc'd to 4.4ghz with HD6950 2g and runs 24/7 for folding and I game on it nightly. If I put a GTX 550ti oc'd into the second available slot what would I be able to use that card for folding@home? What would I need for this ?

How would Win 7 64 bit Home premium handle the two different drivers for the radeon and geforce running simultaneously? Has anyone ever done this?

Mixing ATI with Nvidia or mixing Fermi with non-fermi cards on the same computer generally confuses the folding clients. If you try what happens is the client assigns WU's that can't run on a card and it will spend lots of time EUE'ing.

I can't really comment of the effect mixing will do to gaming but I think I remember that Nvidia's Physix won't work in a mixed video card environment.

This what I heard as well, which is really lame IMO. It's not the exclusivity that bothers me but the fact that you can't use it even if you paid for it. I would love to run a beefy 7870 alongside my 560 Ti for physx, cuda, or even switching for a game in case of faulty driver support.

Thanks for the responses. Not what I wanted to hear of course.

I thought I remembered seeing a review a few months back where this was done for gaming purposes but they did not explore folding.

Probably a Lucid Virtu config.
