Anybody know a good 150$ Graphics Card


768mb is not very much VRAM though, I would stick with a 1gb card. Even a hd5830 would be better in my opinion. If I were him, I would get a hd6850 or a hd5830.
 
to the OP you are definatley going to want to consider oc'ing your cpu a bit to take advantage of some of these cards as the op has a old amd quad (in his member config) that is clocked at 2.5 ghz I believe
