Hello!....i have one question about switching video cards once in a while.Right now I have xfx 4850 in crossfire and i love it. But i'm just curious to compare my ati and would love to buy a bfg gtx 260 max core 55. How would that pan out? Is it okay to do that? once in a great while do a little swicharoo from ATI to Nvidia gaming....just to have the best of both world....Thanks guys....Rafael
