Ok, so I was playing wither 3 running fine then randomly it seemed shut my PC off instantly

I thought this was probably due to overheating my fx8350 seemed to be running high even at idle so I did some in game tests a it has hitting 80, this is with an aftermarket cooler installed, I guessed this may be the cause

So I went into the bios (Gigabyte fx990 ud3) are reset to safe settings, put my required settings back and thought I'd check voltages etc, it seemed to be initiating some kind over over clock or CPU management?.,called core per performance boost? So I disabled it and rebooted to see what effect it would have

Soon as windows booted temps at idea were around 35-40, so I tried Witcher and now underload it's hitting 65 - 70 max... But the thing I don't get is across the board I seem to have gained 15FPS or more in all games!?

Any ideas why this would be the case? Everything running faster, I ran prime95 and it was hitting around 70 after 30 mins

What does this setting do?

Rig

Gigabyte fx990 ud3 Rev 3
Gtx 970
Fx 8350
12gb ram
Sounblaster Z
Samsung SSD
Corsair builder series 750w

PS is that set up ok? What would you recommend improvement wise? Is the MB an issue?

If your CPU was throttling before due to heat, and its not now, that could very well be where the increase in performance is coming from.

The core per performance boost is a feature that attempts to lock every core at higher boost speeds. Eventually, that causes the CPU to throttle downward when the heat exceeds the limit. Which effectively slows the CPU down. WIth that off now, individual CPU cores can spin up and down like they were intended, and you are gaining the performance you have seen.
could be the configuration was messed up and could have been causing problems (in the bios). So by changing the configuration it now runs smoothly because it is now configured correctly.

Great answers thanks! Would the throttling cease with better cooling? would i see even better performance with the core performance boost working as intended??

Im looking to upgrade to a Sabertooth fx990 and NZXT Phantom case, do you think id see a more stable system with better cooling with that set up? I currently have a Coolermaster 430, and its tight and untidy due to no cable management sytem..was even considering if i go down that road getting a H100i cooling sytem...
 
It could. As long as the cooler is pulling enough heat away from the CPU for it to remain at the boosted speeds longer, or even most of the time, then of course things are going to run faster. But, we don't know how far over you were, so we don't know how much cooling you need. And I don't even have the foggiest idea of what kind of cooler you can afford.

Decent coolers start in the low $30 dollar range (212 hyper EVO) and go up from there. Noctua has a couple massive coolers with almost silent fans for somewhere in the ballpark of $75. And then there are water cooling products. Its up to you.
 
Oh sorry, cooler master artic freezer pro 7...I was looking at the corsair h100i, which is why a new case would also needed to house it properly...that's why I thought if I have to rebuild might as well swap the motherboard over to if the asus sabertooth would be a worthwhile upgrade?
