stay away from the fx series i had the fx-6100 and well the i3 outclasses it
The first generation of FX I'd definitely agree with you but Piledriver (current generation) is a huge improvement over the existing architecture. It actually comes close to matching and in some cases beating the i3. It's not as good as the 3570K that's for sure but it's definitely a step in the right direction for AMD.
I checked the 'Source 210' out before. (not a fan of the silver infrastructure of the 'HAF 912' ); I have a question about the 'Source 210', would the extra $10 for the USB 3.0 be worth it? Or will the USB 2.0 be substantial for 4+ years?
I'd say so.
