My main desktop, that I use to game on, is approaching 5 years old. It's a System76 Thelio Mira, and has been starting to show its age. I recently upgraded the CPU to the best I could get, without swapping motherboard, AMD Ryzen 5 5600X. I upped the memory to 64 GB, and the last upgrade I could easily to is to replace my old NVidia GeForce RTX 2060.
