So I have an Opteron 165 clocked at 2.2ghz. Would this be faster that a stock C2D E6300 at 1.86ghz? Go in on the Retail Edge so I have toe C2D and Intel motherboard which doesn't overclock at all. Trying to decide which one to go with......overclocking is an option but would need a good stable board with onboard optical audio output. Should I stay with AMD or sell that stuff and stick with C2D???
