I rocked my Haswell i5 until last year when I built a brand new machine around the 9800x3d. Along the way I upgraded it from 8gb of ram to 32gb, got a gen 1 pcie3 NVME, and went through successive hand-me-down GPUs starting from a GeForce 770 to the RTX 2070 it has now.
In fact my wife is still rocking that machine - although her gaming needs are much less equipment intense than mine. After a small refurb I gave it (new case, new air cooler, new PSU) - I expect it to last another 5 years for her.
I rode out an i7-4790K until this year... replaced solely because of Windows 10 support ending. But it's a solid chip.
My new one is a 9700X. Didn't feel the need to spring for higher power budget for a marginal gaming performance bump. But I suppose that also means it's much more practical for me to jump to a newer CPU later.
Heh I also only sprung for 32 GB of RAM this time, which is still double my 4790K's 16 GB. But I don't use Chrome so RAM doesn't get used that heavily. ;)
I think it's very telling so many people upgrading now are coming from Haswell chips, they are a legendary chip generation, and arguably the last time anyone needed a CPU upgrade short of operating system support or warranty concerns.
Officially it most certainly does not. Haswell chips are fourth-generation processors, Windows 11 requires eighth-generation processors. Though of course, if you bypass the checks it will install anyways.
