Activision, Treyarch and Raven Software have finally released the hardware specs for Call of Duty: Black Ops Cold War's PC edition, and the minimum ones are not bad at all.
Call of Duty: Black Ops Cold War launches on November 13, 2020, so you've still ample time to upgrade your PC if you need to, but if you're gunning for minimum hardware requirements - you might not even need to.
Of course, that greatly depends on where you're from and your personal situation, so we're not pretending like this hardware is free or anything - we're just giving (overly) general estimates.
Interestingly, Call of Duty: Black Ops Cold War's bare minimum requirements mention Windows 7, whereas the rest are all reserved for Windows 10 64bit version.
Minimum graphics is Geforce GTX 670, GTX 1650 or Radeon HD 7950, while minimum CPUs are i3-4340 or AMD FX-6300. Even if you're below these, you should still be able to get these or trade up for less than what the game goes for.
On the higher end of the hardware specs, however, are the heavy hitters, and it's pretty clear that running Call of Duty: Black Ops Cold War at high FPS, 4K resolution and ray tracing will require a pretty penny if you need to buy the gear outright.
The devs recommend Nvidia Geforce RTX 3080, which is a $700 dollar card, and that money could easily buy all the minimum specs gear for running Call of Duty: Black Ops Cold War.
Nevertheless, running Call of Duty, or any other title for that matter, at 4K with ray tracing was never going to be cheap, so it's definitely not a surprise. Additionally, the highest specs will require 250GB of HD space, while the rest of them require 175GB, unless you're gunning for multiplayer only, in which case it's 50GB only.
