Welll... I only recently (IE. 3 weeks ago) upgraded my P4 based system to an AMD 939 system. As much as anything, to get access to a PCIe socket. And got to be honest... by shopping around, I picked up a mobo and half decent processor for peanuts. More than happy with what I've got. Though be doubly happy if AMD do go ahead and produce some faster processors on 939. Though I doubt it myself.

so yeah i think X2 65nm at 3.4/5Ghz could beat a conroe at 3Ghz as long as its paired with CAS2 memory
so yeah im sticking with socket 939 as long as i can and i for one sincerly hope AMD don't abandon a good socket too soon 

however if AMD release a new chip on 939 i shall stick with the trusted socket 939
