Hank_5 :
Thanks I'll try that. But do you mean when all 4 cores are running at 100% and GPU falls bellow 100%, that the CPU is bottlenecking the GPU? and when I turn on V sync does this mean im turning my gpu to perform at 50%/half to what its suppose to perform?
I just dont want my CPU to bottle neck the GPU once I upgrade to a 1440p monitor.
Basically yes. But it's sometimes a little more nuanced than just saying all 4 CPU cores are maxed out, some games are not coded to take advantage of all cores equally. A better way to look at it would be to say that you have a bottleneck when your GPU drops below 100% and the cause is
1 or more of your CPU cores is at 100% usage when the GPU usage drops.
