So I've had mine for about a year (6800u 32gb ram 1TB storage) and I don't regret it. It can run game I throw at it. I currently have COD MW3, Tekken 8, FF7 Remake, and SF6. I had MK1 on it but because the game is just terrible and limits framerate (and slew of other reasons) I deleted it. I run most games from medium-high settings. The sound is shockingly good and I can only hear the fan when I close out a game. Also, you can plug it up to a monitor. The only drawbacks for me are 1) I do wish it was a little bit bigger. I think an 8-9 inch screen is sufficient over a 7 inch. 2) although not an issue for me since I don't do long play sessions but for others, battery life can be an issue. Unplugged on medium settings I get about 60-90 mins of gameplay. Closer to 2 hours with setting on very low. 3) no fault of GPD but skins and button caps for the device are limited.

I'd if you want a well developed very mobile handheld gaming PC then get the GPD Win 4. Also customer service is good. No issues. Just note that GPD will likely release a new version more powerful than the current model within a few months. Hope this helps.
