Spend some time over at Asus ROG forums. Those boys know all there is to know about OC. There is no difference in OC, the theory is identical, no matter what brand mobo, the only differences being what things are called, so you should also Google just what settings to what. (Asus might list a setting as vcore, msi might call it cpu voltage, it's the same thing).

There's a lot to learn, but try and stick to Haswell related OC, as Ivy-Bridge is different, as is skylake Bios. Ivy doesn't have Ring voltage etc and Haswell does.
 
well if i get 144fps without over clocking than i wont have too with my setup, plus ive never overclocked in my life so id rather no aslong as i dont have too lol
 


I'd say 1440p @ 144hz will be difficult to achieve at maximum settings.

On many titles you'll probably see ~100-120 fps avg at 1440p with a few out-liers result in the 90s; for the lighter titles like Doom/Overwatch/etc though, the system should deliver north of 144fps.
 


For Witcher 3 specifically, I believe it'd help if there were extra CPU cores like the 8700k and higher performance DDR4 bandwidth. Digital Foundry showed that in Witcher 3, the 8700k stock 4.3Ghz all 6 cores with 3000Mhz DDR4 delivers better result than the 8700k 5Ghz all 6 cores with 2133 DDR4, ~170fps avg vs ~147fps avg @ 1080p Ultra (vs ~122fps of the 4790k 4.5Ghz all 4 cores + 2400Mhz DDR3; while the 7700k 4.8Ghz 4 cores+3000MhzDDR4 delivers ~145fps avg). This is with the Titan X Pascal which I believe is roughly the same as the GTX1080Ti.

For most of the other demanding titles, it is just the current limit of single GPU performance; almost/around 60fps @ 4k, and almost/around 144fps @ 1440p.

The out-liers that can knock the fps into the 90s @1440p that I am aware of are: Ghost Recon Wildlands, PUBG, Hellblade Senua's Sacrifice.
 
also i wont be playing games at 1080p im going to be playing at 1440p 144hz after christmas lol, so i dont think it will bottleneck/ no reason to upgrade
 


Just to make sure that we don't have a misunderstanding here, I was referencing DF's review for cross CPU/platform performance comparison for Witcher 3 specifically.

The stated avg fps of ~100-120fps for demanding titles except outliers and lesser demanding titles can be seen on Toms review of the MSI GTX 1080Ti Gaming X : Gaming Performance page that show its performance at 1440p&4k with 3200Mhz DDR4 and 6900k, 8 cores @ 4.3Ghz).

------------------------

As I've also said:
For most of the other demanding titles, it is just the current limit of single GPU performance; almost/around 60fps @ 4k, and almost/around 144fps @ 1440p.
So, yes, if you're already on the 4790k, for most games, the limiting factor is the GPU and since there's no other more powerful GPU out there, once you have that 1080Ti there's little reason to do a platform upgrade for just a handful of titles.
 
so far i have been doing over clocking , and atm i have it stable at 4500 without touching the voltage, one question i do have though is what is ring Ratio and should i leave it Auto or should i have it 1:1 with the other? this is my frist time over clocking and so far it has been much more simple than what i thought it would of been :} i was told to atlest go to 4600 with the new Video card im getting for maximum performance but was told i can go even further , any suggestions / thoughts :}?
 
Just downgraded it again back to stock because was getting in the 80-85c range, but I do have a stock fan on it so when I get my new water cooled one it should be much better, any tips for when I do oc it again when my new gear comes in?
 
Read everything you can get your mitts on. Intel won't sell an unstable cpu. Bad for business. But every cpu is slightly different, has slightly different voltage needs etc. So to cover every cpu possible vcore needs, Intel sets the stick vcore high. What you'll find is you'll usually have some room to play around in and never touch the vcore, in your case it might be 4 core at 4.5,might be 4.6 and still be stable. What OC is about is higher than stock speeds / lowest voltage, stable. My 3770k has a stock speed of 3.5GHz @1.24v. Toasty sucker. Right now it's at 4.6GHz at 1.18v. Sure it would still be more than stable at stock vcore, but no need for the excessive heat output.

Apart from Read Everything, the best advice I can give is have Patience. Lots of it. A good OC can take weeks to get dialed in. OC is a hobby, not a necessity as such, so relax and enjoy the ride, rushing or expecting instant results is a fools errand.
 
so far i got stable with no core voltage at 4500 :) thats without touching the volts, although it was running at 80-85 c but my new cooler will take care of that ^^
