Well it's a 3 year old Processor on a dead platform (no new CPU's coming) so you will have to buy a new mainboard if you want to upgrade (13th and 14th gen exist though) Also unless you need all the cores you would be better of with a 9800x3d for gaming in basically any scenario.

4.9ghz is the stock all core max for a 12900k the ks is 5.2ghz all core. I think if tvb is on it can do 5ghz all core. And 5.2ghz on single core which is almost never a thing inside a modern OS More on reddit.com

r/buildapc on Reddit: Did I do wrong for buying an i9-12900k?
December 26, 2024 -
So I just basically almost got yelled at for getting the I9-12900k processor and was told I should have gotten AMD Ryzen 7 9800XD. But I already have my Processor on standby to be built into my PC. So I'm unsure if it's massively flawed or bad or is it really that dire to have not gotten that specific processor and did I screw myself over by getting it.
Update: I finally received the PC so far runs smoothly and the cpu temps have been fine. I do understand peoples concerns future upgrades but I don’t mind dealing with it when the time comes.

in reality, its fine, was it the most optimal choice? probably not. but its a good cpu and will last a long time and unless ur trying to hit 300+ fps in every game cpu matters so little anyways as long as its not hilariously outdated
