Honestly it depends what the build is for, i currently use a XFX 6770 HD, for wow. I run on a 1920x1080 resolution, and settings are all on ultra (except shadow!) and i pull 60 fps, in LFRs/25s it'll go as low as 40, maybe mid 30s. I also am running s 2nd monitor for youtube though, so it completely depends, lower resolution than me? it'll run fine, more intense games than wow? get a better card.
