Battery life for new HP laptops

I am in the process of evaluating new laptops to replace my ancient (almost 6 years) and very pokey Compaq.
I have pretty much narrowed my decision to one of 3 HP Pavillion models. The main difference between two of them is the size of the battery. The DV2727 has a 12-cell battery listed as lasting over 4 hours. The DV2715 has a 6-cell battery listed as lasting 3 hours. Both are 1.67GHz dual cores with a 14.1" screen and integrated Intel graphics. Then there is the DV6757 that has all the same features as the 27xx models, but with a 15.4" screen, discrete 256MB NVidia graphics, and HDMI out (but no high-def drive). The 6757 has a 6-cell battery. All systems have the same 1280x800 display. The 27xx systems use a 65W AC adapter and the 6757 uses a 90W adapter.
What I'd like to know is if a larger screen and/or discrete graphics will drain the battery considerably more than if I got a laptop with a 14.1" screen. This will be my work computer, I plan to use the system mostly for office work rather than gaming and watching movies.
Thanks for your help!
