I think I just had an epiphany reading another thread. I had posting thread after thread on here about how to get more performance out of my system when I just read one and it said that you have to reinstall windows after you upgrade to a new motherboard. I recently upgraded my GPU, Motherboard, and RAM. But I used my existing CPU, harddrive, and CD/DVD drives. When I hooked everything up, all I had to do was boot up my system and put in my XP CD key again and log on. Everything was exactly the way I had left it before I took anything apart. Then I realized that my GPU was getting 3Dmark scores of around 7k, when it should be recieving scores around 10k Would not reinstalling windows be my problem?
