New laptop - faster hard drive or more capacity?

I'm looking at buying a new laptop and am trying decide between 2 similar specs where one has a 1 Tb 5400rpm hard drive and the other a 750Gb 7200rpm hard drive. Other than that they are identical spec and price. Given that I am replacing my old laptop due to lack of hard drive space I was inclined to the 1 Tb but would the hard drive speed make much difference? I would be browsing, photo editing, some video editing and using Microsoft Office apps occasionally.

Any advice gratefully received.
