"narrowing performance gap" with notebooks.
Notebooks may even come close in performance, but at several times the price, with several times stricter thermals. Nobody beats a bang-per-buck humongous air-cooled gaming rig, or the extreme performance in watercooled, overclocked rigs. All the new tech usually comes performance-oriented, and later then they become power-oriented, or thermal-oriented enough to be crammed into notebooks or phones with reasonable battery lives and cold enough thermals to avoid 2nd-degree burns.
Thin-light notebooks that can play games at 4k and 144Hz with RTX 2080 Ti's inside... with power bricks larger than actual bricks, and the ability to melt some surfaces. Hard Pass.
