I got the 5770 and I play all games on Max detail @1080p with solid FPS. Only Crysis and Arcania-Gothic 4 drop below 30’s.
If you can shell out enough for the 6850 then get it, it should work with your PSU (as long as you’re not overclocking and have enough amperage on the 12v rails), as its the best bang-for-the-buck card out there right now, but the 5770 is an amazingly well priced card as well. You should be happy with either one (just don’t go nVidia…)
I got he 5770. Its perfect for my needs! Thanks guys!
