Hey there, I just thought I'd let you know what my experience with the HD4000 is. Look below to see my system setup. I play wow with about half of my settings on medium and half on low, no AA and I play at 1080p. In 10 man raids with particle density set to medium i get roughly 30 fps, but in 25 man raids I need to drop all my settings down to low and I still don't get 30. If you can fit it into your budget I'd recommend getting an HD 7850 or better card. The HD4000 will suffice in the short term but it will not satisfy your gaming needs.
