If you use a laptop to play aoe2, which one do you use?

Also what fps do you get in the beginning of a 1v1 game, and in the late stages where there are a lot of units?

Me: I use a surface pro 4 with an external monitor, I get >40 fps in the early game, but it bogs down to 20-ish fps in big late game fights. It gets worse in 4v4s, so I'm thinking of getting a new laptop
