well unfortunately it took me from 20-30, I want to try overclocking but am not sure how exactly..
Your hardware isn't the issue, neither are your clocks; you've got a rig that can max out WoW no sweat.
It has to be software. Try doing a clean driver install. Use these drivers, and click the clean install option when it's available; it's the 265.90 drivers originally meant for the Quadro line of cards, but is modded to work with Geforce cards. The link leads to the zipped folder in my Google Docs.
Also, open the "Config.W T F" in "...\\World of Warcraft\\W T F" with Notepad and add the line SET gxApi "d3d11" (with quotes) on its own line. That enables DX11 support, and gave me even more frames on my GTX 480.
