Hey guys im sure this is a dumb question but I just purchased an Asus M3a79-t motherboard and it has 4 slots. It says it has support for crossfire. Will multiple nvidia graphics cards work ok in it for folding? I know it cant do sli so its no good for gaming.
Yes, SLI support is not necessary to run multiple nvidia folding cards in a system. Each GPU runs independently so no synchronizing is necessary from one card to the next. I believe this would apply the other way as well, ie you could run multiple ATI cards folding in an nvidia SLI chipset that does not support CrossFire X.
In order to use all 4 slots you will have to use cards with single slot coolers in the last 2 slots. Or you can fit 3 dual slot cards on that motherboard.
