Looking to get a 15 or 16" gaming laptop, primarily to play Dragon Age: Origins 
Absolute maximum budget £850 but happy to go for something cheaper if it is best price for that range.
e.g. i can get an Acer 5739G with the GT240M for £598 which seems a good deal.
Would love to get a Dell xps studio 16 with the HD4670 for under £850 but i think its more nearer the £1k bracket for that one.
Anyone recommend anything? Or have the Acer model how its performance is?
