When you think of PC upgrades, you usually picture a new graphics card or platform upgrade linked to a new CPU. Some people might consider the switch from a hard drive to an SSD as the biggest upgrade they have ever made. If you ask me, the upgrade from a 22″ 1080p 75Hz monitor to a 27″ 1440p 144Hz model was the biggest in my two decades of PC building. The immersion that my new gaming monitor provided was unlike anything I’ve gotten from a PC component. Four years later, I still don’t see myself upgrading my monitor anytime soon.
