As it is currently, you can only submit as a Mobility Radeon HD 4870x2 but there were laptops sent out with a single 4870 installed. Can the listing be changed so that the options would be Mobility Radeon 4870 for single cards and then 2x Mobility Radeon 4870 for crossfire enabled systems.
Thanks!
Here is a screenshot with the card information (I have 2 cards in my system but crossfire disabled)
