im not gaming at 1080 though at 1080 everything is fine. but im on a 4k screen 3840x2160 to be exact and anything lower then its natvie looks horrible.. 1440. looks better then 1080 but the image looks blurd. so i want to have it at native. as it is on this cooler im allready hitting like 64c after 5 hours of prime. 65c after 10 mins of intel extream. and this is only at 4ghz. when i first had this chip 5 years ago i had it on a 4.5 overclock. and it was 1.25volts plus very high LLC.and i think my temps were 64c or something like that.i dont rember.but i have since had blue screens so it became unstable at somepoint and so i have dield it down to 4ghz. temps are worse on the stock cooler as i tested it to compare temps and on that its at 80c on the intel test and 79 on prime. with the corsair its 65-64 my temps are ideling in the mid 40s right now. and this is at 4ghz on a manual voltage of 1.18 with very high LLC also there is a strange buzzing imiting for the cpu itself..it could be the motherboard but it sounds like its coming direclty form the cpu..this is another resson why i wish to upgrade. i allready had to replace the hx1000 psu as my pc started randomly shutting down. and since newere platforms are better and support higher tech thats why i was considienrg the kaby or waiting to see what zen is like or waiting for cannon lake if its worth it.
You are more cpu bound at 1080p though and a gtx1080 dependent on game isn't a card for solid 60fps min @ 4k.
In the games you experience below expected performance, what are your cpu cores and gpu utilisation?
