I've been trying to decide whether to get a 5770 or a 6850 possibly even a 6870 and I've got my eye on xfx or msi
my build MSI 870A-G54 AMD Phenom II 955 (3.2) no O.C. yet new build Cooler Master 912 HAF Thermaltake 750w 2x4 gb patriot wd blue 500 gb
More about5770 6850
Get the best you can afford. If you can afford a 6870 then get it. You may also want to look at the 5870s since they are pretty cheap right now and generally a little faster than the 6870 (more heat though).
Well I'm trying to stay at or below 200 so i was wondering how much performance difference is there between the 5850 and 5870
