This is a 2023 256GB LCD Steam Deck that includes the case, a 512GB Samsung MicroSD card, and a Jsaux 5 in 1 Steam Deck Dock that I have used for AAA gaming and it has been able to run everything I've thrown at it without a bad gaming experience. I swapped This Steam Deck to Windows 10 because it preformed better than Steam OS (the OS it came with). However if you would like me to swap the Steam Deck back to Steam OS then I will do it but it may take longer as it is kind of confusing.
