I'm looking at a laptop at a local used computer store. I believe it's the same as this laptop at this link. Atleast what I know for sure is that it's a Dell i7 - 4600u, there's 16 gb of ram, 2.1 ghz processor (not sure how many cores, and it has a NVIDIA GT 720M. Price is 650, i may be able to negotiate down. Is it a good deal? How's the GPU?
