Zergface My Desktop PC: an i7 4790k CPU and an MSI Z97 PC Mate Motherboard
Although I am saving up money for a newer PC in the future, it still works great despite its age. I've been using it since 2015
I feel like it can serve you up to 2030 with this configuration. I also have a Z97-based PC which I built somewhere around that time as well, and I really do not plan to update so far. GPU is cheap-ass korean 1060, didn't have no troubles so far.
Though I admit I do not play modern games often... if at all. The most graphical modern game I've played is Unreal Engine 4 Vampyr, and I was able both run and record it nicely.
I feel like with a GPU upgrade I can stay with the same PC all the way up to 2040.
My old PC still works as well, along the way... Though if I had money, I'd built couple more old PCs. I have a list of dream-tier parts which I wish I could get my hands on, like GlacialTech UFO V51 cooler, which I wish I will find one day and build the ultimate Win98/XP machine. And, of course, if I had money, I'd upgraded my current PC along the way as well. As I've said, my current GPU is really cheap, but that was pretty much the hobo's choice... and I still haven't moved anywhere from that tier, unfortunately.
