What are the complete specs for each laptop? If you are basing it on the card alone, then no. The 5470 isn't going to be a huge upgrade over the 5450.
Complete spec's are almost identical between them (listed them below regardless). Both are using a i5-430m (anything more is overkill IMO) processor and 6 gigs of DDR3 (for comparison purposes). I also have both using a 1 gig version of the card so I can see the max cost of the system. I am building these directly off HP's website since I get a discount off of them at work. The reason computer 1 is using the 5450 and computer two can use the 5470 is that #1 is an ultrathin and I assume there simply isnt space for the bigger GPU and ability to keep it cool.
