I'm looking to offload my AMD stuff and possibly buy Intel.  Would I notice a huge difference in performance with a P35 board and an E6420 overclocked to ~3.5GHz?  The rest of the hardware will be the same.
also: blah blah blah E8400... I'm trying to break even or maybe spend $25-50 in the end if I actually do this. Assuming I can sell my AMD setup for $175...what's the best I can do? I've seen plenty of 6420s on ebay (OEM) for $125, and IP35-E boards regularly go for $60-70. I'll be using my Zerotherm Nirvana CPU cooler no matter what i do.
