Replying to Need help picking a new laptop

Hello,

I need some help picking a new laptop.

My price range is $800-1100.

I'm looking for a computer that can run Adobe Premier Pro CS6 decently well.

I think I know what I want/need.

I7
12+ gig RAM
Some kinda SSD drive
2gig + video card

So my questions are....

do I really need a video card that is on Adobes approved list? Or can it be a somewhat equivalent card?

Can I buy an external SSD drive and use that for when I'm editing?

Would it be worth buying a laptop with 8 gig of ram and add more myself? Same goes with the SSD drive?

Any help would be great.
