Installing a second ATI Radeon HD 5870 video card to work together in an ATI-crossfire configuration?
If I were to install a second HD Radeon 5870 card, to go with my existing HD 5870 card (using a Y-splitter to get power to both cards from the single pair of PCIe power-plugs), could I get them to work together in an ATI cross-fire configuration?
I'm looking to get twice the GPU power on a single monitor -- not drive two monitors separately. Like what I had with my nVidia SLI setup on my old PC.
Thanks for any help you can provide.

OS X doesn't support Crossfire so unless you're using it for games in bootcamp there's no point in doing that. That being said it would work in bootcamp however. You'll have to use a fan utility to increase your system fan speeds as you're going to be generating a lot of extra heat running two cards. You can use smcfancontrol in os x then boot windows and the fans will stay at increased speeds. good luck
