Update: My Radeon HD 6950 arrived yesterday. I installed it per instructions, and downloaded the latest drivers. I am however not really noticing much of a performance boost in single window or while boxing.

I play using is boxer, two monitors. One full screen, the second divided into four parts. I tried useing the eyefinity but that just made my desktop distorted to where I could not get the windows quite right. When I try to use directx 11 is boxer will not export the file because it is trying to make my toons go to the C:\Program Files. My wow instal is in C:\Program Files (x86).

I will keep working on this, though any advice on configuring the card properly would be welcome.
