probably going to want to upgrade to an x38 or x35 for crossfire, for an intel board, and for sli 750i or 780i from xfx, foxconn, or evga, and the processor, i would recommend the e8400 wolfdale, or the e8500, the e8400 is 3.0ghz and dual core, the e8500 is 3.16ghz, and a dual core, ask some other members of this board for their opinion
