CPU: Dual Xeon vs i7

Hello. Please can someone explain the basics of Dual Xeon processors vs i7 processors for Premiere Pro CS6 editing and After Effects CS6 graphics.

 

If you were to compare a Dual Xeon setup that costs the same as an i7 setup, which would be better for the above and why? Thanks in advance
