I've seen a mint M1710 for sale for £550. 2GB and the 7950 etc. I know theres heat issues with these. But if it was perfect it still a decent mid range gaming laptop. I have a Inspiration 9400 with a 7900GS in it, but its limited to 2GB of ram. I noticed in the past the 7950 was a good boost over the 7900GS and the 1710 takes 4GB of Ram. I'd sell the 9400. Worth the upgrade or not. What alternatives with the similar or better gfx performance for around £550.
