Core i7 System, Poor Performance?

[Fizzler]

I recently built an i7 920 system and have been very pleased with it.

I limited my main to 45fps at all times I am not sure why I would need more at this point.

With 5 clients running the Main on High with the exception of Shadow which is set to LOW I max out 45fps even during peak hours. I am sure I can get more out of it as it remains fairly stable at 45fps most of the times. It drops down to 30fps when I first enter a high traffic area or if there are a lot of graphical elements like portals...

I took this screen shot today while not peak hour it will give you a good idea of what I am getting.

Each slave is set to low on most settings. All toons are running Carbonite, the main is running Lightheaded, atlas loot, and a few other memory heavy addons.
