I7-4770K
I've got my cpu overclocked from 3.9 to 4.6 would that bring any noticeable effects I don't notice the effects. Overclocking my gpu seems to make improvements more noticeable.
it can as long as it is stable. also you need to make sure you have a fan that can compensate for an OC like that or the CPU will throttle too much because of too much heat
It depends on what you are using your CPU on. My OC for MMOs increased my frame rate by 20 to 30 fps. It didn't do anything for 1st person shooters though since they are GPU dependent.
Never goes above high 60's when I'm on any games seems to be ok and been stable for weeks I turned it down recently back to 3.9 and left my gpu over clocked then tried it vice versa and only seem to notice major effects with a lower gpu oc
