I have heard of people having issues but I think people get one problem then auto blame the drivers when a simple reboot is all that is needed. Your OC on your CPU is high not seen many past 4Ghz and unless your on water I don't feel it's stable. I would sugest running Intel burn test if it fails 20 passes or is inconsistent then it's unstable ram timings are also important as eveything has to hit that sweet spot. As for doing bios flashes it's something I advise against as I feel there are just to many things that can go wrong it's asking for trouble. But if your still unhappy then sure why not go for another card as for me coming from an SLI setup with nvidia to my newer card it beats them hands down and I cant see myself going back to the green side for a long while.
