I built my current PC in 2013, and I've finally decided to upgrade so that I can play Doom: The Dark Ages (requires ray tracing GPU and a newer CPU) and go to Window 11 when Windows 10 updates stop (stupid supported CPU list). I've been able to play basically anything I've wanted to until now, so I've never seen a reason to buy anything new. Over the years, I've added 16 GB of extra RAM, replaced my GTX 760 with a used GTX 980 when it died, and early on I added an SSD boot drive, but those are the only substantive upgrades.
Most of the parts came in Wednesday, and the GPU comes in today, so building will commence tonight!
i7 3770k -> Ryzen 7 9800X3D
Z77 chipset -> X870 chipset
32GB DDR3 -> 32GB DDR5
GTX 980 -> RTX 5070 Ti
SATA SSD -> M.2 NVME SSD
I'll reuse my case and PSU.
I can't believe how much more expensive motherboards and GPUs are now. I just hope my motherboard doesn't kill my CPU and my graphics card power connector doesn't melt (how are these things that actually happen now?).
