Ugh... good stuff I asked.
Well, the one pro to the used 5870M machine is that it (ASUS G73?) most likely has a 1080p screen. I'd take it for $500.
the Acer M5: http://www.amazon.co.uk/dp/B00829KE1Q/
the Acer M3:
http://www.amazon.co.uk/dp/B007PPCEO8/
both have a GTX 640 which would be good for light gaming the m3 has a sandybridge and the m5 an ivybridge
the m5 also seems to have a metal case, but its about £50 outside my maximum budget
i realise the zenbook doesnt have the dedicated graphics but its so thin and sleek...
also seen the Acer Aspire V3-571G-9435 for if I want a cheap power house but it has cheap build quality and screen. I'm completely torn between power and build quality
Yeah, that's the thing, Acer dominates this price range as far as performance goes. It's really hard to argue against this particular Acer V3, with it's combo of i7 quad and GT 640M, for £676.97.
Any recommendations for a 1600 x 900 or higher resolution <= 15" laptop? I've got my eye on the Lenovo T430 and Y580, which are both very attractive on sale (regrettably, I wasn't interested in a laptop when the Y580 was $800...), but if there are other models I should look out for I'd like to know about them. Gaming isn't strictly a priority.
