what specs should I get for my new dell E1705?

[deezy455]

Hi, just decided to buy a new laptop, cuz my current dell 5100...only lasts 90min while 4 tabling partypoker, and running PT and PAHUD, so im hoping the new dell inspiron E1705 will solve my problems.
Here are my questions:

1.) Do I need higher than a 1.66 Ghz, if all im using it for is poker (4tabling party, pt, pahud), and basic entertainment?
2.) What is the "Dell Wireless 350 Bluetooth Internal(2.0 + Enhanced Data Rate) [add $39 or $1/month2]
With Bluetooth you can link wirelessly to Bluetooth devices like headphones, mice and more" for? is the normal wireless card good enough?

3) any other specs reccomended?

thanks in advance!
