They are all about the same. However, since you don't have the MB yet, I would research to see which ones use the DDR2 ram which is dirt cheap now. I got mine from Tigerdirect.com and after rebate it came out to $40 for 2 GB or DDR2 ram! DDR is more expensive so try to avoid motherboards that have that.
So, in a nutshell, I would compare both Intel Motherboards vs. AMD motherboards and then come up with the better of the 2 based on the ram.
