Earlier quoted context omitted.
Not sure how heavy SteamOS is, but wouldn't modern games actually prefer a flipped memory configuration? So, 8 GB RAM and 16 GB VRAM would make this a more 'balanced' gaming appliance. But it is advertised as a general purpose PC, so 8 GB RAM wouldn't be enough.
8GB just isn't enough for modern AAA games. Battlefield 6, probably the most highly optimized AAA game to have come out in the past few years, still has a 16GB RAM minimum and Arc Raiders, which is also incredibly optimized, still has a 12GB minimum. Games are only going to become more resource hungry from here, so 8GB in early 2026 would be a terrible idea.
Runs pretty poorly on a RTX 4080 with 5800X3D @ 1440p.
It also legitimately looks worse than the Battlefields that predate it, even up to Battlefield 1, which is over a decade old now.
A better example is Arc Raiders.
