First of all, the temperature can be an issue - without a cooling platform and regular thermal management, you can forget about running ultra+ graphics, as some games from 2000 will still make it quite hot.
However, it can run Cyberpunk on ultra settings and anything lower in requirements. (2023-2024 games ULTRA Settings OKAY)
Secondly, it can handle a large number of browsing tabs, a game, and Telegram running simultaneously, as long as you manage the temperature. ( and crypto mining )

Additionally, it's still a DELL product, and DELL has some software issues. They are mostly fixed here, but not completely - once every few months, the laptop may lag, and only a restart will resolve it.
To turn off the fancy keypad light and other lights, you need the Alienware software.
AND KNOWN ISSUE:
Also, some games won't work on your display (you'll see a black screen only) but will work via HDMI on your TV (don't ask me why). This issue is still not fixed. And by the way, if the HDMI is disconnected, the laptop screen will remain dead until restarted (reconnecting doesn't solve the laptop screen issue, but you can still use it on the TV even with a dead screen on the laptop).
Games affected (confirmed) - CSGO, Stalker series, Deus Ex, and some others.
Now, the interesting part is - sometimes it actually would work without HDMI, but the screen might freeze suddenly or become unresponsive.
