I watched the video, and honestly it's pretty rough, especially considering he was using a slightly better GPU for the test. This thing is definitely not a 4K60 machine for modern games. Even if it occasionally reaches that, paying around $750 for a box that delivers 40–60 FPS on low settings with FSR set to Ultra Performance is just terrible.
I love Valve, and I get that the economy around pc parts is a mess right now, but it really feels like they dropped the ball with this one. I know they're not aiming to sell 50 million units, but damn, this is flat-out disappointing, and at the price they're aiming for, it's basically DOA.
If Valve really wanted to price this thing around $750 or above, they should've beefed up the hardware and accepted losing money on each unit. The goal should've been medium settings 4K60 with FSR4, not whatever this is.
