i5 3450, sapphire nitro r9 390 8gb vram and 12gb ddr3 ram 1600mhz.

Thought about upgrading to i7 7700k with 3200mhz ddr4 ram and at some point a gtx 1080.

Im playing pretty cpu intensive games including early access ones, mainly: CS GO, Rust, PUBG, Battlefield series and the list goes on.

Is me thinking my cpu is bottlenecking my system after it served me for more than 4 years a correct assumption?

Well, they didn't get to test with Ivy Bridge CPUs for Battlefield 1, but for the testing they did do (https://www.techspot.com/review/1267-battlefield-1-benchmarks/page4.html), a Core i7 didn't provide any additional performance over a Core i5, even with a higher clock speed. And the drop from a Core i5 to Core i3 is more to do with dropping from a 4C/4T CPU to a 2C/4T CPU than the clock drop. And at 1080p resolutions, the R9 390 is going to be more of a cap on your performance than the i5 is (https://www.techspot.com/review/1267-battlefield-1-benchmarks/page2.html).

And especially for CS:GO, I doubt you're going to see a whole lot of difference. Your i5-3450 isn't much slower than the the i5-7400 Techspot used to compare against...

that processor would struggle a lot to run nowadays games, the gpu also probably kind of strugglin. if you are kinda on budget, get ryzen like ryzen 5 1400, but ryzen overclocking capability is not as good as the intel processor, but it is less expensive however. i do rather get the 6700k if it only pretty much used for gaming, the performance different compared to the 7700k is not really noticeable, it only perform really slightly better, and maybe when overclocked it will perform better

Your i5-3450 isn't much slower than the the i5-7400 Techspot used to compare against the Ryzen 3 CPUs (https://www.techspot.com/review/1463-ryzen-3-gaming/page4.html), so it shouldn't have any trouble at all with CS:GO.

If you're going to get held back, it's more likely to be your GPU. Best way to check it:
-- Try increasing the resolution. If your FPS doesn't change, your CPU is holding you back. Otherwise, your GPU is the limiting factor.
