It looks good, better than the current design, it looks more like a whole instead of the seperate rectangles we have now for the logo, the banner, and so on.
What I like about the current is how the active buttons in the left and top menu attach to the background of the main screen, if you know what I mean. It would be great to have that incorporated in the new site as well. It looks like you started to do this already (as the buttons on the beta site fit seamlessly on the central part) but I fear the sub-menus in "downloads" and "forum" might screw that 'everything fits together' feeling. Then again, that might change completely once you start fiddling with the colors.
The logo itself is nice, the right size, and the right place, the way I see it.
Overall, a good design, and I like it.
