Upgrading GPU/CPU, need advice

[foley]

My “current” build is one I built a few years back. I’m running a i5-6500 and a gtx1060 6gb, with a z170a gaming motherboard from msi. 16gb ram. I play shooters (modern warfare, cs:go, valorant, apex, etc.)

 

now here is where I get confused..

I just bought a used 8gb gtx 1080 founders edition for $310. After installing it I found out with the current cpu I have there is quite a bottleneck. I searched up what cpu I should get to match my 1080 with and I ended up buying a i7-7700k... for $500.
After doing further research I feel like I should just upgrade my whole computer. The stuff I’m buying is overpriced and old. Any tips? Should I just build a new pc or stick with my 1080 and 7700k? I know my motherboard is a little older now too. the cpu I purchased came out in 2017 and feel like for the amount of money I spent I could have gotten something way better. I might return it. Any input would be appreciated, thanks

The 7700k is definitely dated, but still a decent gaming CPU. If you do want to change out, I would strongly recommend going with an AMD system, like a B450 Tomahawk Max with a Ryzen 5 3600 as a great pairing that will last you for many years to come.

I mean the Ryzen 5 3600 is under $200, where I just spent $500 for my cpu. If I were to build a new pc I could definitely up the budget some.. ($1200?)  I were to build a new pc with a even better cpu and gpu than what I got now what would you recommend? Maybe 2070 super with Ryzen 3700x? I just feel like a new pc would last way longer than what I have purchased

Definitely. You already have the DDR4 RAM and as long as its at least 3000 speed you're good there. So you would have to get a mobo, CPU, GPU... you could likely get a 3700x, a 2080 super and board for under 1200
