the 7800x3d is probably the sweet spot on performance/price right now, you should be able to get a decent b650 mobo and 32 ram on those 500 pounds
There is right now a scare on ddr5 ram price (just check the posts above yours). Usually i would advice to wait for black friday but if the cpu is already on sale (since you mentioned the price) might be worth it to pull it now in case ram keeps climbing, hard to say
