bro if can, wait for upcoming new gen cpu this year.. i once owned fx8350 and now using i7 4790k.. from my honest experienced, indeed i gain some improvement like 5-20fps average in all games.. but does it really matter? even with fx8350 i can play every game so smooth always getting 60fps and above.. running heavily OC dual r9 290s and no sign of bottlenecking..if you oc the fx8350, the performance gap will be closer.. to me the upgrade only give me bigger number in fps and benchmark.. but in gaming experienced still the same.. unless you are using 120/140hz monitor. if using 60hz 1080p the gaming experience will still be the same.

if you can sell your fx8350 and the mobo with decent price, then its ok to upgrade. to me its not worth to spent almost RM2k just to get only 15fps more.. save your money for new gen cpu and gpu.. fx8350 is still a reliable cpu atm for sure.
