Here's one comparison I was able to Google:

It's hard to tell just how "fair" the comparison is but it may give you some idea. It makes sense that even a 2.8Ghz dual quad 2008 Mac Pro would be a bit faster than a 3.0Ghz dual quad "old" Mac Pro because of faster bus speed and newer processor, but I don't think the difference is all that great and for the same price as the old model 3Ghz model you can only buy a single quad core 2.8Ghz 2008 model. Plus, the refurb 3Ghz old model has the Radeon X1900 XT 512MB graphics card which is better than the ATI Radeon HD 2600 XT 256MB that comes standard on the new Mac Pros (you can buy the option 8800 GT card but that adds another $150 onto the cost).
