Ok, I'm kind of new to SLI and I was wondering what the difference is between 750i, 780i, and even 790i, I know the higher the better, but what will a 780i mobo get me, that a 750i mobo won't.
^^ The 790i is just overkill. Not only is RAM going to cost you a fortune to buy, the board itself (if you buy eVGA) would cost at a stunning $100 more than the 780i.
