Thank all for quick answers) Definitely drop fx-9370 from my list. But also I have some limitations in my budget so can't afford i7 4770k and decided to consider its little brother core i5 4670 thus would be appreciated to hear some feedback about this model too. But one small detail I also want to know: what do you think about amd FX-9590, it is worth to pick up one or core i7 4770 would be better choice?
Since you're looking to do gaming at some point, which graphics card were you looking at?
Haven't decided yet. Want to choose CPU at first.
Alright, I guess it's more important for your uses. If it was a purely gaming rig then its best to work around an initial graphics card selection IMO.
Out of the 2 you said, the 4770 would be better. Essentially, anything up from FX 8350 (actually FX 8320 IMO) loses its price/performance and the intel wins out from there on. So under $200/£150 in my opinion is AMD territory, and above is intel. Once again, just my opinion before anyone goes nuts at me.
The intels have less cores, but they are much stronger. The FX has more cores but they're weaker. Either are perfectly capable for gaming, I guess it depends on how many cores these programs you use utilise, how much processing power they need, and how much you want to spend. But yes, the i7 4770 beats the nuts off the FX 9590.
The i5 4670 is essentially the i7 4770 without hyperthreading. For your needs, I'm guessing the i7 would be better. And the only difference between the 4770 and the 4770k is that the k version is unlocked and you're able to overclock it.
