So between the base 21.5" model and the higher end 21.5" model - there is a £250 difference. Within this £250 difference, the only two things differ are: 500gb additional hard drive space Better graphics card (ATI Radeon HD 4670 w/256mb) I guess my question is, who will really benefit from the extra 'Umph' graphics card? When would the graphics card really kick in? I mean, I am not fussed with boot times because it is already super duper fast. Who is the ATI specifically aimed at - what application would really benefit the ATI card? EDIT: p.s. apologies if this has been posted elsewhere, did try to search prior to posting - but found nothing.
