GPU: I'm going to be running off the CPU's integrated HD 3000 graphics until the releast of BF3. At that point, I plan to upgrade to whatever is necessary to run the game at max, or as close to max as possible. I'm thinking CF 6950s, but I'm not sure yet, and I don't think anyone else is as well
Some have more ports SATA and USB, better power management (power phases), there are boards with better crossfire/SLI compatibility and so on but the end of it is if you don't need those features they are a waste of money
Oh I see. About the CF/SLI: can a motherboard only do either one? I don't mean doing both at the same time, I mean are motherboards only capable of doing one? The motherboard I have selected says SLI, so I'm wondering if I will be able to do CF if I choose to instead of SLI.
