can anybody Recommend a good second hand upgrade that will compliment a 2070 Super?

Hi.
This is a bit of a weird one. A family memeber recently paid for me to upgrade my PC as a thank you as I am caring for a family member. I gave my old 2070Super GPU to my partner.
She mainly plays older games with the odd newish one thrown in. She mainly plays Sims 4, WoW and games like this. Her current system is as follows

i5 6600k
2070 Super
16Gb (8x2) DDR4 ram.
850W psu.
According to a few bottleneck calculators shes being bottlenecked by the CPU (understandably) However, neither of us have much money at the moment as I am caring for a family member and im unable to work and do that as well.
I was just wondering what would be the cheapest CPu to go for that wouldn't really bottleneck the CPU? Her current board would allow a i7 7700k but it's not really much of an upgrade according to benches. I'd obviously have to upgrade the Mobo As well and as she has RAM already it would need to be ddr4 compatible. She doesn't play the latest games as i said above etc I'd say the budget is £200.. Is this even possible? thanks for any help

You could get a 12400F and H610/B760 motherboard or a 5600/5600X and B550/A520 motherboard.

They're both 6 core, 12 thread CPUs and have a decent uplift in single core from the 6600K.

6600k to 7700k is a surprisingly decent jump. 4 more threads and better clocks makes a difference between unusable and ok for most games. Especially if cooling allows to set a mild overclock as well, from memory it should do 4.6 GHz no problem on any cooling.
My 2070S was paired with 6700K for a long time, did ok.

16Gb (8x2) DDR4 ram.

what speed is this ram?

a ryzen 5600 + a320 mobo would be the cheapest combo
this would cost ~£100 if you get it from the right place

not wrong, however the 7700k is not worth it, as it carries a price premium because it's the best chip for the z170/z270 series boards
incidentally, the price is also within spitting distance of getting a used 5600 + a320 mobo
i'd rather pay the extra and get a much better platform
