MBP Retina external graphics card support via thunderbolt?
Does anyone know if using an external graphics card via a thunderbolt PCI chassis is supported yet? I know Sonnet and some other manufactures have began selling Thunderbolt to PCI chassis, but was not sure if external cards are supported by Mac OS X yet. Seems like it would be a powerful tool if one wanted to upgrade, say their 13" MBP from the standard intel GPU.
