This is a great option for boosting performance on Alienware systems with a compatible port. The GTX 1080 FE fits right in and works great with the latest mobile drivers installed from NVIDIA. Huge performance boost in games and it keeps the GPU heat out of your system, which should extend the life of the components and lowers fan noise from the laptop to only the CPU fan. It also adds 4 USB ports, so it is a kind of docking station. If you know that you are always going to have the cable connected when at your main work space, the hub can be useful for external hard drives and such to reduce desk cable clutter. The unit is very big - with the rather inflexible cable in the back it probably takes up at least 18" of depth and certainly makes a statement on a desk. I was able to hide it down in a desk cubby, but for many you need to realize it is going to be a substantial part of the look of your space. It does have one of the light up Alienware heads on it that has a full channel LED allowing for it to be controlled by the AlienFX software that also manages the laptop lights, or can be shut off too. One last quirk - with it connected the sleep and hibernate functions won't work anymore. All you can do is shut down or restart the PC.
