Does any have a source to buy the crossfire cable for a laptop? The desktop ones are too short. Alienware won't sell me one because I don't have an account with them. You have to be the original owner to get support from them. I bought my laptop and a second HD3870 card from ebay. I can't find the cable anywhere.

Are you sure the laptop has the ability to run two cards in crossfire? Remember, laptops can't be upgraded, in order to fit two graphics cards, it would have to have had two to start with.
It's a gaming laptop. It had a free pci-e MXM slot for a second video card. Which I purchased and installed myself.
