The San Diego's are good coresm if you are just planning to overclock on air or water then those chips would be prefect. The Clawhammer scores don't clock too well with standard cooling and they need the subzero temps to start clocking nicely.
Yeah I plan to just overclock using air cooling to start out and then maybe move to water cooling down the road if the need be. So I think the San Diego will do quite nicely. Thanks for the help!
