So the idea is I buy all the components for the bulk of the computer based around the Asus PRIME X570-P X570 board, but since CPU and GPUs prices and availability is currently a mess, I buy a second hand 2200g 1st gen Zen off ebay for like £80, which will cover my CPU and GPU needs until sometime later in the year when the 5000s are better available and much cheaper. Right now if I wanted to buy a 5600X plus a basic passive GPU, I'm looking at about £450, which is silly. By the end of the year I can spend the same money but instead get a basic GPU plus a 5800x or even an 5900x for the same money, so I think I'm better waiting for a bit to buy those. The 2200g is still a 30-40% benchmarked improvement over the 6650 i7 in my Surface Pro 4, so I still get a speed bump, and most importantly I can build a functional and reliable system, since my SP4 is pretty hopeless now and the screen is almost dead.
So, constructive feedback from you all would be appreciated

I've got a MOTU M4 btw, if that raises any red flags. I don't need to connect anything else to the computer other than USB MIDI controllers.
Cheers.
