The 2000 series is ok for laptops, for 1080p playing is more than enough. Who is gaming at 4k on a laptop?? If you want to play at 4k at 100fps as they admited then buy full desktop machine. There will be maybe 15% boost to 2000 series in laptops department. Thats nothing!
Which laptop is better in terms of cooling, fan noise? I am struggle between 2 of them. The only downside for proteus is lack of thunderbolt3 and high noise from fans.
