[halodude23]

Hello i've been having a hard time choosing a combo or just a single card for my computer since the GTX 260 got returned due to the failure of the Power Supply Plug.... Also i am not using money to buy it but Points so you dont have to recommend me the GTX 295/285/275 and yeah.... Heres my Combo Choices Nvidia 9800 GT 512 MB+Corsair Hydro H50/ Radeon XFX 4850 512 MB DDR 3+Corsair Hydro H50 Or Single Combo Nvidia Geforce GTX 260 896 MB DDR 3/Radeon 4890 or 4870 but not the x2.. Thank you for your recommendations...

The best card out of the ones you listed would be the 4890.
