It's basically a GPU and its memory on this small square shaped PCB board. On one side, it has the PCI-Express interface. If your notebook supports MXM, you can swap and upgrade GPU's as they come out. I think nVIDIA even came out or is coming out with a SLI MXM solution for notebooks. Basically the motherboard of the laptop has two PCI-E slots for TWO MXM GPU's that you can upgrade. There was also this graphics card that MSI had a prototype of at CeBIT 2006 where it's this PCB with two MXM PCI-E slots, but the PCB itself is in the shape of a normal graphics card and plugs into a PCI-E slot.

Here's a great site about MXM:

There's usually a heatpipe attatched to it inside the notebook. Then it's connected a heatsink with radiator type fins which then has a coaxial fan blowing the hot air out.

HDR uses quite a bit of your systems resources. Whenever I looked down at the beach where you start Lost Coast from, it lags like a bitch.
