In my ceaseless quest for a new laptop I'm now choosing between these two: - http://www.saveonlaptops.co.uk/Lenovo-Z510-59395010_1536137.html - http://www.saveonlaptops.co.uk/LENOVO-Z500-59399412_1533701.html Summary: i5 3210M vs i5 4200M 4gb vs 8gb GT 635M vs GT 740M Price difference is £130 ($215), a not inconsiderable amount. Simple question: is the more expensive one £130 better for what I need? It's mostly for web dev and music production. The older i5 is gonna bes lower than the newer, that's obvious, but it doesn't seem from what I've read that I should expect a huge difference. Are there any important "instructions" the 3210 lacks? (I don't even know completely what instructions means, I've just heard it in CPU talk...) I'm feeling the cheaper one; I can chuck more memory in, and the GPU is fine for me as gaming is way down the priority list (though I'd like to fire up HL2, Doom 3 etc - nothing that recent.) Unexpectedly, NotebookCheck seems to report the 635 as achieving the better FPS in the like-for-like game benchmarks I looked at, even though the 740M has the better specifications. Thanks in advance.
