Hi guys, My 3870 is playing up making lines all over the screen and one hell of a noise - I'm thinking of getting a 5770 from Apple so I can have the boot screens. I don't want to mess around with flashing etc and don't have access to paypal or ebay to buy second hand. If I spend the rediculous £200 on an apple 5770 can I pick up a generic PC 5770 and crossfire them together for gaming under windows? I mean rather than spending £200 for the 5770 and another £200+ for a high end line PC card wouldn't crossfireing 2 together work well? I mainly play strategy games and SW:TOR but my monitors are 27" 1600 x 1200 so my PC 4850 isn't that good. Let me know your suggestions, Cheers!
