Chaps, I'm retiring my desktop PC and really just want a small laptop for my GOG games.
I only want to spend around £500 - £600? Suggestions?

I am tempted by this (screen size appeals to me, don't want a monster laptop).
Alienware Mx11 : http://www.dell.com/uk/p/alienware-m11x/pd

This comes in at £450 (last years model hence price).

But i'd like to hear from you guys :)

I may be horribly wrong on this, but if you just want to play GOG-type games, keep in mind that dosbox is currently not multicore, so between a setup with more slow cores and one with fewer fast cores, the latter would perform better.
