Notebook video card

[DerekT2008]

Sorry, I know these are hated topics, but......... also I did a search, didnt see anything that helped.

Anyway, trying to decide between a few different Notebooks, most noteable would be the Dell 1730. Need opinions?

What video card set up would be best?
single 8800 gtx 512mb (not the dell) VS
sli 8700 256mb (dell) VS
sli 8600 GT 512mb

Any help would be greatly thanked, also opinions about notebooks in general.

Thanks
