Re: New build, need opinions.
The only difference I see between revs 1.3 and 3.3, is that 1.3 just has a slightly lower model audio chipset. Not a big deal. The power between the e6320 and e6420? You mean the speed or power usage? Theres no big difference between them. Except the e6420 has a high stock speed by like 300MHz, and a higher multiplier. But both have the same overclocking potential. I'd go for the e6320 though.
