Unsure of what my next upgrade should be for my gaming rig

**Current specs:

CPU: Intel i5 10400F

GPU: RTX 3070

RAM: 32GB (2 x 16GB) 2666MHz DDR4

Motherboard: PRIME H410M-E

SSD: 480GB (Windows 11)

HDD: 2TB **

In short I'm stumped as to where I go upgrading my current rig. Various bottleneck sites suggest my CPU might not be able to keep up with the 3070 which might hinder FPS and performance, but I also know that for the most part this information cant be trusted.

Main reasons for wanting to upgrade include doing away with the extra dongles I have for Bluetooth and Wi-Fi which aren't always reliable and futureproofing.

I'm currently hanging my nose over an MSI B760M GAMING PLUS WIFI Motherboard and i5-12400F processor. I could get both for just over £200 right now, but don't really know if this would be worth it, or if investment would be better placed elsewhere. I've not considered GPU update because a) EXPENSIVE and b) current information seems to suggest that 40 series GPU do not have much bang for the buck.

So the question, what do people here think makes sense to do?

Thanks in advance!
