If you need to ask here to find reasons to upgrade, you may not need anything dedicated or the price tag that goes along with it.
Do you have reasons you think you should upgrade?
Personally for my current (low volume) projects, I am on a virtual server. $20/month. It currently does everything I need, and the price is right.
On the flip side, I am just now closing shop on a dedicated server that I required to host a site that's no longer viable. There were technical performance reasons I required a dedicated server for that.
Only problem I've had with the virtual server is that it couldn't handle a high "slashdotting" type event it got recently, although that could be solved with an upgrade of resources. Things like that are a technical reason to upgrade. If you're not running into reasons like that to upgrade, you may be fine with what you have.
