Andrew Cunningham:

The Core will fit “virtually every popular desktop graphics card from AMD and Nvidia,” which should encompass most mainstream cards. The enclosure includes a 500W power supply, and Razer says that cards that consume up to 375W of power will fit—this is enough for dual-GPU monsters like Nvidia’s GeForce GTX Titan Z, cards that require that much power are rare.

While not a completely elegant solution, I would love something like this for my 13″ Retina MacBook Pro – an external GPU which has enough horsepower to render Final Cut Pro X projects. This would allow me to have only one Mac at my home office, instead of a desktop and laptop.
