Do I need to upgrade my 2600K??

[Brand24]

I'm purchasing an Acer Predator X34 shortly so all my gaming will be done in 1440p.
I was wondering if I really need to upgrade my CPU, MB and RAM before I get the new monitor.

Currently playing Ashes of the Singularity, WOW Legion, GTA V, BF1 and BF4.

What are your thoughts or experiences with 1440p gaming requirements?
I'm only gaming on the PC no multitasking right now or in near future.

My current PC specs are;
i7 2600k oc to 4.5ghz
ASUS ROG GeForce GTX 1070 Strix
ASRock Fata1ty Z68mb
16gb DDR3 1866
Thermaltake litepower 700w psu
240gb SSD in raid

No, not at all. It's still very competent and you only have a GTX 1070. Now if it's something like SLI GTX 1080 Ti or Titan Xp then MAYBE on the very rare chance it could very lightly bottleneck you.

I should be fine still and for a little while longer yet. It's still a solid CPU for Gaming and you have a nice Overclock on it by the looks. Going up to 1440p won't make it work much harder than it did at 1080p or whatever Resolution you were playing before. CPU usage doesn't scale very much with higher resolutions especially compared to GPU usage which increases quite a lot obviously. With a GTX 1070, i wouldn't expect any of your above games or most modern to begin with to have any performance issues or major bottlenecking with your CPU. Hope this helps

From a pure numbers standpoint, clock for clock, skylake/kabylake has about a 20% improvement over Sandy Bridge.
So your 4.5 ghz is like a 3.6ghz 7700k all things held equal.

BUT, if you are only gaming and and at 1440p which shifs the load to the GPU over 1080p. The relative performance difference shrinks.
And if you get a solid 70FPS and a 7700k gets 80FPS, from real world perspective you won't perceive a difference

I would not suggest to upgrade your 2600K either.

I will stick with my current system and see how it pushes at 1440p
Many thx for your help
