And as for why the E6600 is more expensive, for a start, they are not made any more, and they remain the overclockers choice over the E6750 because of the more variable multiplier (6-9). The E6750 is (6-8) so demand for the E6600 is high.
And if he gets only a single 2GB stick, it will run in only single channel mode and not dual channel.
I still don't think 6-8 and 6-9's difference is worth $40. Plus, if you get the OEM versions, they're cheaper. (and since you're using aftermarket coolers, theres no point in spending on the stock coolers)
I've found the OEM E6750 for $176 and the OEM E6600 for $215.
And is the E2160 story really true? In that case, maybe he should consider doing that.
And single-channel vs. dual-channel performance has been proven to be rather negligible. And i'm quite sure there ARE 2GB DIMMs in existance that run in dual-channel.
