acually it's a 400MHz clock difference between the 3200+ and the 3400+.....
but yeah I probably will go with s939 just for the sake of being able to upgrade alot further.
I may not be able to overclock this system at all because it is not for me. I'm building this system for my uncle and I'm not sure how he feels about overclocking.
Anyway I'll go with s939 then for the reason I said.
