Who Should Buy the Steam Machine
- You want a console-like experience with PC game prices
- You've never built a PC and don't want to learn
- You value unified warranty and support
- You mostly play indies, older AAA, or competitive games at 1080p/1440p
- You're fine with the 8GB VRAM ceiling
Who Should Build Their Own
- You've built a PC before (or are willing to follow a YouTube tutorial)
- You want 12-16GB+ VRAM for 4K or future-proofing
- You like upgrading your GPU every 3-4 years
- You want to choose every component
- You're comfortable with community-supported SteamOS builds (Bazzite)
