You mean Athlon 64? There is no 65....
ABit is the next best OC'ing board IMO. Preferably the AV8-3rd eye if you want AGP, AN8-3rd eye for PCI-E which also has nforce 4 chipset opposed to the AV8 having via.
3500+ winchester core is a good OC'ing CPU. If you want to save a few more dollars though, go with the 3200+ winchester core also good for OC'ing.
