As an upgrade thought, that box should be able to handle dual X5675's, which are fairly cheap on Ebay.
There's a very noticeable performance improvement from (eg) the E5645's, let alone the E5620's.
Saying that as I used to use a self build box (Supermicro motherboard) with dual E5645's as my desktop, but it always "felt" a bit slow. :/
Had the opportunity to upgrade to X5675's, and now it "feels" fine interactively due to the higher base and boost clock.
The highest model, X5690's, from all reports are literally no faster in use than the X5675's (maybe thermal throttling?). So not worth the extra spend. ;)
