Since i didn't register to your forum, the only problem i see is the banner that is out of line.

You might want to scale your banner.
You have to keep in mind that most users do not have a 22 / 23" screen
Indeed, on your resolution which is for 22 and 23 inch screens your banner is good.

On the other hand, the banner fits also on 1280x1024...
To me it looks like an offset problem. Looks like the left offset is much higher than the right.
Check out:
ACP --> Styles and Templates --> Edit stylevars
Search for: Header --> Header_margin

If left and right are set to 0, what happens?

Edit:
I found this code for the banner in your header template:

<div id="header" class="floatcontainer doc_header">
	<div><a name="top" href="forum.php?" class="logo-image"><img src="http://i.imgur.com/hRjwe.jpg" alt="BAC SERIES - Desarrollado por vBulletin" /></a></div>
	<div id="toplinks" class="toplinks">

In here I see that the image is not centered.
You might want to do that if the offset is correct.

Just put this in front and after the banner code:

<div style="text-align:center;">
   YOUR BANNER CODE
</div>
