buying a 9300...some questions

[Perseus]

buying a dell 9300 laptop and I have some questions...

I am planning on using two monitors, and I have read conflicting advice. If I buy the 128 video card will i be able to run both at 1600x1200 resolution without problems...or will the 64 do me just fine? Also, I am currently running 1020 x 760, so do I need to go more than 1600x1200 to eliminate overlap?

...is it worth upgrading from the processor from the 1.6mto the 1.73m...

...what is the difference between the 60gb and the 60gb 7200rpm? Is it enough to pay 120 bucks?

How do people like their 9300's...can I playing 8 tables, listen to itunes, run pokertracker and playerview on two seperate monitors at the same time without any lag? Cause thats what I'm going for...

thanks guys
