Built myself a new PC today. Not necessarily for playing games but my old PC still had parts from pre 2010 so the replacement was overdue. GPU didn't support 4k even though my TV can output it. Couldn't even stream Youtube videos in 1080p without heavy stuttering or freezing.
Holy hell GPUs are expensive nowadays. I tried to get one of the cheapest that still had at least some power and it set me back 240 Euro. That's a beginner's GPU that can't run last gen games any higher than 1080p 60FPS (so maybe PS4 Pro comparable?). For the same kind of money I used to get almost high end GPUs 10-15 years ago.
So in total I spent 650 Euro for a new PC that's barely more competent than a PS4 Pro (except the CPU which should be far better) and it would've been 700 Euro if it wasn't for the old power supply I can still use.
What I'm trying to say is that Series X is an absolute steal. A comparable PC costs at least 900 Euro (without OS).
