I've recently downgraded by Q6600 as well, since realizing that my usage does not really require a quad-core chip. The most CPU intensive use for me is using PCSX2 emulator, which can only utilize 2 cores.
My Q6600 clocked to 3Ghz only (I think limited by my board, a GA-965P-DS3). I opted for a used PDC E5200 for $50, which clocked to 3.6Ghz pretty easily.
I haven't sold the Q6600 yet, but I expect that I'd gain about $100 from this downgrade. I actually even see a slight gain in performance running PCSX2 from the clock increase.
