Well after doing what everyone said in this thread and deleting my WTF folder (gay!) i am now running 2 WoW accounts on Ultra setting with 50-100fps. TYVM to everyone in the thread for the quick and polite responses!
Not sure if it was completely deleting an old ATI program and reinstalling Nvidia, running Error-Checking on my hard drive (never done it before), or even deleting old Realtek sound drivers but something helped and thank you all again!
