Nope used 4790k's go for more than a 2600x
Selling.his build and going 2600x/3600 would be the way to go.
4770k are 100-120, 4790k 140-180.
The fundamental that everyone has ignored in this thread is that in the op' he says he is gaming at 4k using an Rx5700XT and wants to know of a cheap and noticeable improvement.
So there will be minimal improvement from his intel system to an Amd at that resolution with that gpu. The problem will be the 4 threads saturating in games that are multi-threaded and demanding.
It's still a viable option and cheaper to sell his 4670 and put it towards a 4770k or 4790k, than to buy a whole ryzen system. No point buying a 2000 ryzen should just go straight to 3000 series. However I agree he can also sell up the intel system and put it towards a newer Intel or Amd system.
Copied from my last post like this.
my observation of quite a few threads, titled '' i5 2500k/3570k/3770k/4670k/4770k should I upgrade?'' and when DDr4 prices were outrageous, I always advised that if you are on an I5 and have 16gb of system memory, then sell the I5 and upgrade to the I7 it will transform the system for a minimal cost. Then wait it out until Ryzen is good enough and Dddr4 prices are realistic, and if you are on an I7 just clock it and keep it running until you feel it's holding you back.
Well that moment is right now, DDr4 is cheap enough (especially E die), with rumours of price increasing back to ''.... off stupid'', and Ryzen 3000 is good enough to actually consider now. Whether you choose Intel or wait for the next gen of Intel is another debate
