Hi. Im new to the forum. I need some advice for a important decision. I have a choice of the previous-gen 2.66gz 15" MBP VS the New 2.66 15" MBP.

Here are the SPECS:
Previous-gen: 15" 2.66/4gb/320gb/9400m+9600mgt "512MB" w/ExpressCard

New-gen: 15" 2.66/4gb/500gb/9400m+9600mgt "256MB" w/ SD slot

The reason i am thinking of buying the OLD one is that it has SATA2 3.0gigs speed (FOR FUTURE SSD) + Also a 512MB 9600MGT over the 256MB version GPU, and is cheaper (a deal) than the new one.

1. What is the difference between the 2 "discrete" 9600mGT cards (256MB VS 512MB).....Is it much improvement? (I think it will be for Snow Leopard).
2. How much better or good is the NEW 7-hour battery compared to the Previous gen model?

The battery may be a deciding factor. I heard the new one can go for 7-8 hrs on the 15". I think its a bout 4.5hrs on the old one?

Anyway this is going to be my 1st Laptop and 1st :apple:, so please assist me! THANKS in advance :)

If it helps, I have the new 3.06, just got about 6 1/2 hours with mixed usage(video, wifi, itunes etc) and on the older machines you would get anywhere from 2-3 hrs, so for me the battery improvement is worth it, but it is an individual preference
