Hey, I have been looking at laptops for a while, and found that the Acer Aspire E5-573G-59C3 seems to be the best way to go, for cheapest $500 range. but I have been wondering something. With laptops, you can't just put in any gpu like with my desktop currently. I have an r9 270 and this laptop will be my main, I would like to know how cpu and gpu upgrades work with laptops, as I would like to look into that. I am not asking if I can put my r9 270 in it, I am asking why not and what can actually be put in there instead. Thanks!
