Might be worth going into PC Wally World just to have a look at all the laptops (if you haven’t already!).

My Vaio is still running strong after 4 years the only thing I did was reformat it and reinstall windows to get rid of the trash that all laptops seem to come with these days…

Don’t get too hung up on the processors you honestly won’t notice the 0.2 seconds faster word load time. 😉
Have you considered saving a bit more cash and looking at a Mac? Well worth going into an apple store just to browse (just leave the wallet at home!!) some great little tools for photo editing.
Good luck, its never easy as the markets move so quickly. Maybe find reviews from 3 months ago and see if you can pick up a bargain now for a laptop that was 3 months ago the bee’s knees.
