7.04 has done a really incredible job with hardware compatibility… I haven’t noticed a problem with my machine or any other I have installed this on… being that its a laptop, i would assume its going to use common hardware, so it should be fine… and for the older machine everything should work perfect too…
Game, yes… they are a pain in the ass to get working… Dual boot if you are a hardcore gamer
