ludus :
If you had a mobo that supports both SLI and CrossFire, would you be able to utilize both, or only use one at a time? I know there is a FAQ for this but i could not find the answer. Thanks!
You can't SLI AMD cards, and you can't Crossfire Nvidia Cards. And if you meant to have a mobo with a minimal 4 slots and to have 2 cards from Nvidia SLI'd and 2 AMD cards crossfired, then no, because you can't run AMD and Nvidia in the same system unless you do some hacking or some stuff.
Even if it would be possible, it's preety stupid if you ask me. It's a waste of money to have 4 cards, 2 by AMD and 2 by Nvidia.
Cheers
