Well i have a Alienware aurora 2009 and the graphics card is pretty outdated. But i can still run crysis on insane settings, battlefield 3 medium- low settings, and minecraft well perfectly.I dont think it cost much you should look for this if you really want a low price graphics card. If your insane go for this AMD Radeon HD 7970 GHz Edition.
