I need a graphics card that's better than my old one that will run DirectX 11=. My budget is $150 at the very most, but under $100 would be preferable. Is such a thing possible?
Current specs (simplified form because I don't feel like looking them up this second):
AMD Athlon X4
750 GB hard drive (w/ plenty of space)
6GB RAM (3x 2GB cards I think)
nVIDIA GTX 315 w/ 512MB (DirectX 10.1)
...and a 23" monitor
