Darkbreeze :
Probably not at all. With that build I doubt you'll be able to game at ultra settings on really demanding titles at all. The 960 AND the FX-6300 are both somewhat middle of the road budget options, not high end enthusiast hardware. You can probably do high settings at 60fps @1080p on most titles. Some titles might require further lowering of settings while other titles might easily be run at ultra. I'd also say that within two years your CPU will be severely limiting your gameplay.
you broke my heart ,dude
anyway i still have an option to change my processor but i cant extend my budget to buy an i5 k variants
i can somehow manage to get an i5 but starting versions only
is i5 even worth the extra bucks
so to sum it up i have 3 options:
1. buy fx 6300 and buy a cooler and overclock it
2. buy some other amd processor fx 8320
3.buy i5 3rd gen or maybe 4th gen
4. to stick with fx 6300
P.S -i will have to do a lot to get those extra bucks to buy a better procesor than fx 6300
so keep it in mind and tell me the best option which is totally worth those extra bucks
