As I'm still using Windows 7 I've been getting notices about support ending and needing to upgrade to Windows 10. They are also saying that since my PC is a few years old I should consider getting a new one.
As far as I can tell my PC runs great, but I haven't tried any 2019 games. Mainly I've been playing Deus Ex Mankind Divided, Batman Arkham Knight, and Doom and I can run these games on pretty high settings.
I built my PC a few years ago and here are the specs:
Core i7 2600K CPU @3.4GHZ
Geforce GTX 1070
Intel SSD5 512GB and Samsung 850 Pro SSD 256GB
Considering the hardware above and that fact that it's working fine for games so far I don't see any reason to upgrade anything. Do you?
