Okay, I have another GPU question. I say another because you can't go five seconds without hearing "Do I get X or Y?" Anyways, I won an XFX HD 4770 on ebay that was practically brand new for 66 dollars, so it was a good price. However I have a second chance offer on an HD 4870 512mb for 63 dollars. However, the deal with that card is that it needs a bios reflash. The owner's friend flashed it and from the on it would restart or show a black screen. So do I go for the safe option or do I go for the risky reflash and the more powerful card?
