What are the temperatures on your current CPU at this stable OC's? Maybe you are reaching a point where you will need a better cooling system to achieve stability, no matter what CPU you fit into your system...
Also, you are talking to get 200Mhz more? I don't think it worth the effort (unless you've already give up on selling the brand new unused CPU).
If in your situation, I will sell the second CPU and buy some water cooling components, or a high end air cooler, and try to push my 1st CPU.
The CPU never breaks 68C under prime at the current OC. Temp is definitely not the issue, but to run a higher oc I need to use voltages that are way beyond the accepted safe zone for this CPU. I'm thinking I'll just sell and live with my modestly acceptable 4.4ghz. It isn't what I expected when I bought the CPU, but it isn't terrible and I guess it isn't worth the hassle of switching processors.
