I'm upgrading my old Core2 Duo and i have 2 CPUs in my mind i5 4570 & FX 8350 the reason i need a new CPU is for better multitasking , software development and a little gaming(games it's not my main concern so don't start about better gaming performance). The price for each of the systems is the same(i don't have the money for more expensive i5 or i7).
