World of Warcraft Ultra
I want to be able to play WoW at ultra and be able to have high FPS. What one graphics card do you reccomend please be under $175
I played WoW MoP at 1920x1080 on Ultra (questing & 5 mans without dropping below 50fps) with my OC'ed 6850 1gb. In your price range a Radeon 7850 1gb or 2gb is the best bang for the buck.
Sapphire Radeon 7770 1gb
XFX Radeon 6870 1gb
XFX Radeon 7850 1gb
PowerColor Radeon 7850 2gb
(In order of price and performance)
Also since you're simply asking about the GPU I assume you have the PSU to back these up? Also, if you're going be raiding 10/25 mans I would definitely suggest the 7850.
Edit: I added the 7770 simply because it's pretty darn close to the 6850 (should be able to run Ultra @ 1080p) and it just gives you cheaper option.
