It looks like essentially 3 mobile cards (MXM or something... if forget) all plugged into a big host board. I remember someone doing something like this a while back with 2x ATI GPUs. Just an awesome card though, I love the 4x DVI!
so the board is an MXM to PCIe interface? Then in theory, wouldn't this make the card upgradable if a beefier MXM module came out? (I say in theory because MXM modules are next to impossible to find)
