Thank you, the budget is under £750 (originally was £700). The 3300X certainly does perform better for gaming and is cheaper. Completely missed it. What would be the drawbacks of it though? How can it cost less? What would having fewer cores affect?
Also why change out the mobo? Is the one I had not compatible with Ryzen 3 CPUs?
You also switched out the case, could you please explain why?
Sorry for all the questions 😬
That B550 has better voltage regulation, which will prove useful, for upgrades, and also helping to ensure you don't get held back, for boost clocks, due to poor power delivery. B550 doesn't need a bios update, for the 3300x. The B450 board might need said update. Unlikely, due to how poor stock levels have been, but still a possibility. B550 also has support for PCI-E 4.0, for graphics, and the M.2 NVME slot, that uses the CPU's PCI-E lanes. B550 is also slated for guaranteed Ryzen 4th gen support. B450 may or may not get the one way bios update, for said support. The only real negatives of the B550 vs that B450 is the wireless controller is slower, and the on board audio isn't quite as good. If you never intend to overclock, you could spend a little less, and go with the A520 version. The boards are identical, other than chipset. You could then step up to faster ram, keeping costs similar.

The 3300x costs less, partly because it is a 4c/8t cpu, which is still enough for gaming. 1080p is more CPU dependent, than higher resolutions, so you want the improved IPC, of a 3rd gen CPU. The 2600 is a bit inflated, price wise, though due to supply being lower. You can view the price history, on PCPP, for the CPU, and see it is more expensive than it was, just a few months ago. I changed the case, solely to keep the pricing similar.
Something interesting to watch, with regards to GPU scaling, with the 3300x.
