Howdy, I'd really reccomend buying an AMD prebuit with a socket AM4 motherboard like this guy to start out with https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F193010146504 , an AMD a4 system has a lot of upgradability for when your friend's budget improves and you can fit a decent gpu on the used market in for the price of this prebuilt. As this system runs you can probably run a somewhat consistant 60fps in medium 1080p on these titles. I have run an optiplex that I got from my college surplus with an i7 2600 and a geforce 645 oem for the past few years with decent results.
