Question CPU Upgrade

[jam500]

So I'm wanting to upgrade my CPU as it bottlenecks in certain games like AC:Odyssey. It is currently running at 4.5Ghz and I will be overclocking my next one as well.
My problem is the LGA1150 socket on my motherboard leaves the i7-4790k as the best upgrade but only offers a slight 8% speed increase. First off, would this be fast enough to avoid ALL bottle-necking and secondly would I be better off swapping out my motherboard as well so I can get a different CPU like one of the new AMD Ryzen 3rd Gen?

I'm not wanting to spend a lot of money ($400ish-usd) so upgrading my MB isn't ideal but I have a feeling I'd be better off.

Another thing to note is I will eventually be getting a 1440p 144Hz monitor so I need a CPU that won't bottle neck at 1440p as well. Any help is much appreciated 😀

You could get a decent cheap MOBO from Intel or AMD and then get a 200-300 dollar CPU if you go that route let me know and I can help you decide a CPU

Yea might do, which AMD CPU would you recommend for gaming at 1440p with an rtx 2070?

The soon-to-be-released/reviewed 3600, 3600X (and up) are rumored to rival 9700K in actual gaming frame rates (so we hope!), so, those might be some reviews worth waiting on....(NDAs lifted and the onslaught of reviews should commence pretty early and promptly on 7 Jul)
