Usually its the die that determines compatibility, some dies are fine being mixed, some just hate each other
 
Verify with thaiphoon burner or if you have no heatspreader look at the ics themselves
 
Btw what ram do you have right now? A pic would also be helpful

oh and an extra stick of ram, if you only have the 1 already, id add that too. but i dont reccomend intel stock coolers, so you should probably upgrade that too, but thatd be the 3rd thing, 1 paste 2 ram 3 cooler. especially if that cooler was working fine for you first, otherwise, maybe ram 3rd

@El Diablo Before getting a new stick of ram most motherboards say thatand also it is recommended they be from the same kit.

yeah, ill definitely try that, thanks for help

Its probably the paste, if you do want to shell out a few extra bucks on a cooler while youre at it, going to something like a cooler master hyper 212 from an intel stock, will be a pretty good difference. wouldnt spend much more money than what that costs. make sure it fits as well, im not sure if it does, just something along those lines

Considering it's at 83 at 50% useage a new cooler will help. The stock cooler was barely able to cool (and often just wasn't enough) the 3770 so getting a new cooler will help.

All i see is you running above 140fps with ease. Clean the case and fans. Get some new paste. If you want more performance, get a new CPU and GPU combo

What am I suppose to look at?
I see a screenshot of 143 and 183fps at a certain moment in time. Is this relevant? Is this bad?
 
You probably need to clean your PC and apply new thermal paste if it runs at 80 C at 35%
