Was given the card by a friend to mess around with today so I've been doing just that. My only issue is that running through hdmi (Haven't tried other connections yet) I get black bars around this game.
I had the issue with the desktop but it was fixed by setting overscan to 0% in CCC. Now It just haunts me on COH. No black bars on WoW. Just the one other game I have installed. Any ideas/help would be great. Two hours of google searches didn't help.
I ran into the same issue when running on a 46" HD TV over HDMI. However, I was using an nVidia card and they give you the option to manually resize to fit the screen, using sliders to adjust it. I don't remember if CCC offers such a feature.
