The width is fine, I think centering it is what it needs. I agree that the blue icons should be customized and maybe change the font used on the top red bar where it says "For gamers, by gamers". I'm not really feeling all the white at the top, perhaps make it the same gray that you have under the logo?
Loving the red and black combo, the sideshow is great and the navigation is very original. Might be a little cluttered, some things not really necessary such as the calender. I also don't like how I can't see how many posts or threads are in each forum.
Hope that helps a little.
