Since you do want to game, I’d recommend going with a computer with an amd DGPU. Nvidia is mostly fine from a driver standpoint. Also Nvidia does have cuda so you might actually want to get one with an Nvidia dgpu.
Get something with an Intel wireless card, that’d be the best case scenario. I’ve had weird issues with both realtek and Broadcom. Lots of amd laptops come with mediatek based wireless cards, idk if they work well in Linux.
Tbh I’d rec any laptop that fit your requirements and install your distro of choice. (bunsenlabs for me).
They don’t show pae support so some OSes have issues. This is specifically for the first generation. I have a Pentium M 735 laptop which shouldn’t have this issue but for whatever reason PAE enabled OSes such as 32 bit Ubuntu won’t boot. I probably screwed something up. It currently runs bunsenlabs helium as it doesn’t require PAE. I’ll amend my previous comment
