I got a new computer about 2 weeks ago with 1TB hard drive space, 6gigs of ram and 2gigs of dedicated memory on my GeForce 520 Graphics card. The worker at best buy who is a friend of mine told me that I would be able to run World of Warcraft on Ultra settings without any lag or fps issues, however I am experiencing these issues and can only run on Low.

Is there anything I can do to fix this? I was able to run this fine when I got the computer out of the box, but now it is not working smoothly on Ultra. Also, when I turn on my computer it says the Catalyst Control Center is not compatible with my Graphics Card driver, however I am not sure if that has anything to do with it there. I use a DVI cable to connect my graphics card to my monitor.

My computer specs are AMD A6-3600 APU with Radeon(TM) HD Graphics 2.10GHz 64-Bit Operating System.

This was an expensive computer, I would prefer to avoid buying anything extra.
