Built my midrange PC in 2012 and a month ago after getting advice from GameFAQs both times and I've had zero issues so I don't see the problem. The 2012 PC can still play games, it's just slow primarily from all of the random shit I've installed over the last 8 years and not having and SSDs
If TC wants a comparable build, here's mine from a month ago
CPU: Ryzen 9 3900x Mobo: Gigabyte X570 Aorus Elite Wifi GPU: GTX 2070 Super FTW3 Ultra Air Cooler: Noctua NH-U9S RAM: Corsair Vengeance 32 GB 3600 MHz Storage: 1 TB WD Black SN750 (Windows 10 Pro OS) + 1 TB Samsung Evo 860 + 2 TB WD Blue 5400 RPM Storage: 1 TB Samsung Evo 860 (Ubuntu) Case: Lian Li O11DW Dynamic (Black) PSU: EVGA Supernova 750 G+
Minus the extra accessories like the monitor, keyboard, mouse, and extra case fans + extra cpu fan (installed after above pic was taken), it ran me just north of $2000. Drop some storage and upgrade the graphics card to a 2080 that isn't overpriced and that's pretty much what TC would have.
