I have a question regarding Windows 7 and Windows 8.1. I'm using Windows 8, Windows 8.1 since few days without problems, I have no driver issues or other problems. However, I have a HD 4870 1GB, and my question is whether Windows 8 and 8.1 is the best choice for me, or at least Windows 7 for best performance? I use the computer mostly for playing games and for the most part for surfing, so flash videos, etc. I do not know whether there are differences in performance between browsers in Windows 7 and 8 because of the hardware acceleration and others. GA-MA770-UD3; AMD Phenom II X4 920; 4GB RAM, ATI Radeon HD 4870 1GB Thank you!
