If you really want to go cheap as chips, then get a second hand GA-965P-DS3P or DS3.
I had an E6300 on the 965P-DS3P for 3 years up to 2 days ago running 3.4GHz for 2/3rds and 3.1GHz for the final third (got another set of 4GB ram with different timings and speed that made it not as stable).
I have ripped off the E6300 and am now running a Q9650 from ebay @ 3.91GHz. Had to get another 4GB twin though that was identical to the best pair I had (8GB total).
So yeah I can vouch for the GA-965P-DS3P (rev3.3) from first hand experience. You can even crossfire it with two gpu's! The DS3 version is equal in oc'ing but no crossfire.
