Hi Guys! I have a question that needs answering. At the moment I'm running an Asus GTX295 in my pc. It's a great card but I want to upgrade it. I'm thinking about a GTX480. What I need to know is, (and I admit that I havn't done a lot of research) if I can run a GTX295 and a GTX480 in SLI? The one is a DX11 card and the other is'nt. Would that give any problems? I've never run video cards in SLI before so I'm new to that. Thanks in advance!
