You do have a tremendous number of options, i personally recommend getting something pre-built WORKING desktop at the moment in the $600 range, you could get an alienware laptop but i just don't trust it and they are very expensive. If your graphics card is not good enough, get a new one. Here's my current desktop build and it works just fine, i only have problems with the software. This works so well i've just bought the standard ATX version of this mobo and a similar processor to replace my busted old windows desktop:
-Rog strix B550-I gaming motherboard
-Ryzen 5600G
-G.Skill DDR4 RAM (16GB single stick)
-Inwin case with built in 150watt power supply for specifically mini-ITX cases.
-Samsung EVO 2TB M.2 hard drive stick...these are faster than your standard SATA SSD drive and compact/neato.
-nocturna low-profile fan
They make carrying cases for micro-atx cases, this whole machine could fit in a 2 small backpacks....EDIT: the desktop can easily fit in any small/standard backpack, peripherals with the small monitor i have now (not in picture below) could fit in another...
I would not recommend emulating this build since you seem to want a to game and a graphics card would not fit in this case. A picture of my build can be found in this thread:
Turns out, low profile cooling fan doesn't fit in mobo and now i have to return everything again. How lame. People in the computer industry often talk about "human error", but what this means is that computer error is inevitable, and while i was never a believer anyways robots will never be able...

Also,
this is very important, beware of every other motherboard that uses the AM4 sockets, many of them do not have an updated BIOS,
and flashing the BIOS doesn't always work, i've been driving back and fourth to a computer parts store for finding simply a motherboard and processor combo that work, fingers crossed trying this next one today, using a B550-F Rog strix. Do your research before buying ANYTHING, i blame the pandemic era for this failure in manufacturing, other people have been having different problems with computer parts as well, today is a bad climate to build a computer. Just buy something prebuilt that already works and customize!
