Only played d3 and stwor so far. What game or program would be best to test it? Also would overclocking be pointless or worth doing? I think i read somewhere that in amd ccc to put all sliders on full or something lol. Is msi afterburner good or bad?
GPU : Yeah MSI tools are very good. Afterburner is great for monitoring your GPUs whilst gaming (temps, load, vram usage, fan speed, core speed, vram speed, ...), and also video recording. Much better and lower resource than fraps. BTW, I would just leave the card at stock for a while. It should be plenty powerful as is. It's best not to start moving sliders about if you are unsure.
I wouldn't bother with Kombustor (which is basically Furmark), do a couple of Unigine pass instead. Check your results with similar systems just to check if you are not getting any weird performance issues.
RAM : check on RAM profiles in the BIOS. It most likely runs are stock speed (1333MHz). Load up the XMP profile (should be an option fro that in the bios), or set the RAM manually to 9-9-9-24-2T. And if the VRAM defaults to 1.65V, try lower it to 1.6V, and then 1.55V. Run memtest86 overnight for fault check. If you start having errors when lowering the voltage (or if the RAM defaults to 1.5V), bump it up a little bit again. But the RAM should theoretically work at 1.5V, 9-9-9-24-2T.
CPU : If you overclock, run Prime95. OCCT / IntelBurnTest are a bit like Furmark for CPUs. They are OK to run for extreme conditions, but you would never get into those situations in real term anyway.
CPU-Z, HWMonitor are tools you can use to monitor system health and status (clock speed, RAM settings, temperatures, fan speeds).
If you use manually overclock, go for 4.4GHz, which would be the sweet spot in terms of performance, temps and voltage. Should be achievable on that cooler, and not too stressful, while giving you a 30% overclock.
Then check the Vcore value when at 4.4GHz. I would try lower it under 1.3V, but certainly under 1.35V. Depending on the chip, can be stable as low as 1.25V, to 1.325V. The lower the better for temps and CPU stress.
OC Genie should put you at 4.2GHz(?), with safe volts. TBH, that should be enough.
