What are you planning to run in 1080p? Games, MKV's, porn? Lol.. Are you planning to go CrossfireX or SLI? If you're doing just video playback @ 1080p then any 5770. If you are planning to game @ 1080p then 2 Galaxy GTS 250 in SLI or 2 Sapphire 5770's in CrossfireX would be just what the doctor ordered!
