"The GT 220 is nvidias 40 nm part and has DX10.1. Since it has a 64-bit interface I think it's just an updated 9400GT, but no one really knows since it's an OEM only part that no one has bothered to test . Anyway $100 is not worth it for that weak card. If you're gonna buy the dell then just buy it as is and add in a much more powerful Radeon 4850 which costs under $100 now. That's if the PSU can hack it anyway. If not then a 4670 would be a good and cheap option while still being faster than the GT 220."
