I was thinking about possibly getting another SSD instead so maybe that's the best option to go for here can never have enough of them
Is it worth thinking about Intel? I know their clock speeds are better so guessing that would make that the better option if it's solely for gaming?
Space consumption of some games can be insane so better to have good amount of SSD space to not need soon more:
Modern Warface requires 175GB, which might take most of old SSD.
Also with limited number of NVMe slots that 1TB is sensible minimum when not having shoe string budget.
Basic/entry level DRAM cacheless NVMe would be actually £109, but that budget easily affords higher end drive.

If you like having web browser, possible voice chat etc on background 50% higher core count is going to win little higher per core performance in future.
With next-gen consoles bringing 8 cores/16 threads as base level in fall/before Christmas, heavy games of the future will expect to have lots of cores exclusively for themselves.
In few years heavier PC games could well demand more than 8 cores to perform best.
Also improved architecture Zen3 CPUs will be BIOS update compatible with current AM4 boards.
If improvement is anything like between Zen+ and Zen2, those are going to take single core performance crown from Intel's Skylake rebrandings.
Which have who knows how many more vulnerabilities to patch.
Intel simply didn't give a damn for security when it kept improving performance to surpass AMD last time and speculative code execution etc have more holes than Swiss cheese.
Also on Intel platform you'll be stuck at that 8c/16t.
As for possible other improvements instead of very expensive, and half assed design, motherboard what you have in that other side of gaming immersion, sound?
If you don't have actually good surround speaker set, good headphones with binaural sound simulation can give very nice immersion with even feel of distance besides directionality.
And without cost/placing&space requirement/room acoustics problems.
Very comfortable Beyerdynamic DT990 (open design for quiet environment) and DT770 (closed design) can be gotten for £100 level.
Sound cartd capable to driving most available headphones and good binaural sound simulation isn't much more.
