Go to this link: http://www.sony.co.uk/customise/vn-fit-e
Then click on 'select and configure' for the vaio fit 15E. Choose the i5 and Nvidia 1gb special offer for cpu and graphics card, select the 1080p display. Then you can choose more ram, a bigger hard drive or a touchscreen, but these things aren't necessary. This laptop will easily max out Rome 2 on the 1080p display
. Also it is only 25mm thick and has a backlit keyboard, so is portable. You should get it quick before the special offer expires.
Hope this helps, I think it's a great deal!
