I upgraded that weak card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102994)
to this one:
GeForce GTX 750 Ti (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502)
for $149.99-$30.00 rebate.
I can run World of Warcraft on ultra settings with no lag, and its lovely!
I ran into one problem while trying to install the software for the graphics card. The setup.exe file kept freezing and under task manager said it was "Not Responding." I tried booting from the disc, and uninstalling the AMD Catalyst Control Center that was currently installed on the PC.
The solution I came up with was downloading the software directly from the company's website http://www.geforce.com/drivers/results/80913.
No more bumps after that!
