Hmm. Not that it is big deal, but I would be somewhat worried about true longevity with the VRAM. Not sure if SteamOS helps there, but on PC some new titles are going over the 8GB VRAM.
it meets or exceeds the ps5 and xbox series x, so it might not be top tier, but it'll be fine. I have a plenty good time on my series x, cant think of any stutters.
