You can still 100% get a great 2nd hand gaming pc for that amount. That will play all games, including all console games from every era, and will last for 10 years at least. Also you can use it to make music / art / software and also do most jobs.
A lot of sellers will even throw in the peripherals for free.
I might buy up a few now while they are left.
Also never buy 1st hand desktop hardware, total waste of money, the price drop from 1st hand to 2nd hand is insane, but desktop components dont degrade that much, theyre still mostly following IBM's sane design pattern, so you're getting a massive price drop with no downside.
You can't play Pokopia, DK Bonanza or Mario Kart World on PC. Even with a 5090. You also can't play Cyberpunk 2077 on the plane or train with a 2nd hand desktop unlike the Switch 2.
....and how are you going to carry that gaming PC onto a plane?
Like, it's a portable console, it's not a competition for a desktop PC in any way.
