Depends on the game, the only game that I know of that you will have CPU bottle neck is supreme commander and in that case you have no need for a graphics card of that magnitude. Your normal shooter games will have no problem with that CPU. But along with everyone else you do not need the crossfire configuration. You would be much better off purchasing one high end card then purchasing another high end card in a year. You will have spent less money and it will perform fine for games today, and perform much better for games a year from now.
