I am In need of a new gpu. My gpu is an xfx radeon 6670 clocked edition with 2gb of ddr3 ram. This card I just found out is 6 years outdated so I need another gpu for $150. It needs to be pci-e 2.0 x16. The problem is, my cpu is and amd phenom ii x4 830 clocked at 2.8gtz. I don't know if it a strong cpu but I have to stay with it. I need a good gpu that will perform well with no bottlenecking. I really need actual help here. Also I cant overclock my cpu because my pc is an OEM pc from asus. So help is needed.
