I bought a slightly used 280x from eBay and installed it yesterday. I upgraded from a 7770 and the performance really inst much different. Certain games will have a slight improvement but still feel choppy. The game concerning me the most is GTA 4, its running hardly better than the 7770, no matter what setting i cant get it to stay above 30 fps (unless i put everything on low). Even with the settings the same as i had them before it only gets a few fps more than the older 7770. What am i doing wrong? I have tried installing the drivers from both msi and amd websites and the amd one does perform better but still not good. I'm a little concerned if it has something to do with the dual bios switch thing sense it used. If you have any ideas or questions please let me know. Thanks!
