Hello, I have a problem with my ASUS AMD Radeon HD 7770 GPU; about a month ago I got infected by some sort of malware that messed up my Windows 7 x64 installation (probably was a registry problem since it messed up most file extentions). While this was happening I was getting terribly low FPS in games like World of Warcraft and Minecraft, to a point which were unplayable. I went ahead and reformatted my whole hard drive and installed Windows 8.1 x64 from scratch. After reinstalling the latest AMD drivers and the games themselves I was still getting the same terrible FPS in the same games. You might say that it is a bottleneck with my CPU, but I have been rocking this PC configuration for a year now with no problems whatsoever. I am posting my rig below, hope you can help:

CPU: Intel Core i3 530 @2.93GHz
GPU: ASUS AMD Radeon HD 7770 (2GB vRAM)
RAM: 6GB DDR3-1333MHz
Storage: 1x 1TB Hard Drive
PSU: 500W
Mobo: Some sort of ASUS socket 1156... don't remember the rest

Thanks in advance.
