Computer dummy needs specs

[RagahRagah]

Am I to assume the type of NVIDIA is irrelevant as long as the computer is current? And is that to say that if it doesn't have an NVIDIA card that it's entirely a no-go? I found the exact laptop I linked that comes WITH an NVIDIA card but a lot of reviewers are complaining about it making the laptop really buggy (messed up drivers, IIRC). I have been looking at Alienware but I don't want to spend all that money on a laptop in which I'm only going to play less than a handful of games.
