Asus reveals more details about the Immensity motherboard

The GPU on the board turned out to be a Radeon HD 5700-series, most likely a 5750 and the product manager mentioned that it's extremely difficult to cool the GPU on the motherboard. The whole idea behind having a GPU on the motherboard is that the Lucid Hydra chip will automagically boost the performance of whatever graphics card you chose to add to your system. This sort of makes sense, but not for the additional cost of having a GPU on the motherboard.
