I'am pretty sure most mobo's are PCIE 2.0 or lower end x16 so I'am pretty sure it's better to get a pc as rest of compants cheaper and also we ablity to upgrade in future don't fucking argue with me you silly boy
if you get home you connect the video card trough the laptop card, as simple as that. laptops cant have decent cpu's in them and most just have onboard intel gfx, which are fine for most things except gaming. so it would make an excellent add on for any laptop if you ask me :)
I heard motherboards have one all ready
It's not as if he has an overpowered laptop now that he can use in the train :P
