Is a CPU going to be a limiting factor in being able to make use of say a GTX 1080 and a high quality monitor with a spec that can display at a high refresh rate at 1440p ?

If the CPU is going to be a limiting factor by how much ?

Lets say the CPUs in question are the k versions of Intel i5 or i7 stretching from sandybridge to Skylake

Forget about upgrading for now as that config will last you a couple more years and put that money that's burning your pocket to better use: a gtx 1080 like you said, a big ssd if you don't have one already and, last but not least, choose one of these babies:

They have the same panel and features and are widely considered to be the best gaming monitors ever made, and for good reason: 34" 21:9 1440p 100Hz IPS with G-Sync(which is a must!)


No. It migh have been at 1080p, but not at 1440p. Regardless, the way the industry seems to be going, i would go with the 6700k.

The "problem" I have is that I have cash burning a hole in my pocket and I fancy upgrading my PC. I use it mainly for work (not video editing etc) and gaming in FPS titles ++.

My current system is i5-3570k with an R9 290X and plenty of ram on a z77 board running at 4.3 GHz. My monitor is a budget 27 inch and i have just sold 2 others that were giving me a triple monitor setup. I also sold another r9 -290x that I had in crossfire.

I am getting Oculus rift.

I am fairly sure I want a GTX 1080 for a little while and a high end 1440p monitor.

I am not sure I can justify moving to an X99 or Z170 motherboard and K series CPU plus DDR4 on top unless the gains are really worthwhile.

I do have a a sensible option to farm off my current PC to my daughter for whom it would do for several years (although she isn't hankering after one just yet) or sell off the bits.

Like a lot of people, i have been tweaking and adding bits and pieces for several years but feel like a complete new motherboard and cpu combo for interest.


There are plenty of people saying you want to be on Skylake and X99 but the advice seems more about a few fps in benchmarks versus real world noticeable +benefit or need (for VR or 1440p at high refresh)

I quite like the idea of overclocking for fun but it seems the Z170 is all about memory overclocks between the main boards on the market and the Braodwell-e chips don't seem anything special over and above current generation. So id be buying for vanity not much performance (wouldnt I?)

When it comes to motherboards I am not excited by leds and high end audio or wi-fi, front panels etc and more by raw speed and reliability. I am not bothered about the latest case fashion and put off a bit by designing a water cooling loop when AIOs and graphics cards coolers - see mt odo the job with a lot less fuss (and cost)
