Above is a link to the summary page, but the results are similar for MainConcept H.264 encoding:

Basically, a 6 core Intel i7-980X is a little more than twice as fast as a quad core Intel Core 2 Q6600 and about five times as fast as most dual core CPUs. A workstation with two of the new 6 core 5600 series Intel Xeon CPUs will probably be close to twice as fast as a desktop PC with one Intel i7-980X.
Since Vegas pro relies on CPU speed, this should give you an idea of improvements that you might see. The results in the article are more or less consistent with John Cline's render test Vegas project. Obviously, other factors such as the amount of RAM and CPU clock speed will also determine overall performance using a given piece of software, but this benchmarking article gives you a good idea of whether you want to spend some money to save time.
