dell 9300 vs. 6000

i know both of these support wuxga screens with 1900x1200 resolution. but is it worth the extra $$$ for the 9300's 17" screen vs. the 6000's 15.4" screen if they both have the same reso? does the extra 1.6"s of screen really help the eyes or is the 9300 just too damn bulky? any other benefits to shelling out extra $$$ for the 9300? i would only be using it for poker. any thoughts would be helpful...
