After my last deployment I got a Lenovo Leigon Y740. it comes with a RTX 2080 Max Q and 17 " Screen. I play everything from arma to withcer 3 maxed out. It does get really hot if you play for longer than a couple hours unfortunately but i just got a fan pad that's about the same size and it dosen't have any issues.
They do a really good deal for any first providers and military
