Really curious about this, as the power draw is 195W, which is great for non-cubix setup, where the amount of cards start to tax the mac pro power supply.
Comparing it to the the GTX 285, 205W & 240 Cuda cores, The GTX 680 is 195W & 1536 Cuda cores.
I'm very curious, but this might look like the new base card, (one that would slide in very nicely in the PC box I've slowly been build as well...).
