Right. Thunderbolt is here, it has been here for a while now, and i'm curious to see what the potential really is for this port. Now some months ago i've seen some rumoured Thunderbolt to PCIE slot cases (whatever you want to call them) Heres some links: http://www.magma.com/thunderbolt.asp http://www.sonnettech.com/product/echoexpresschassis.html http://www.theverge.com/2012/1/10/2698168/msi-GUS-II-external-thunderbolt-gpu-enclosure i'd really love to have this, but somehow they are all only for like 100-200W usage, and my question in this thread is, isn't it possible to make this sort of box with an external power source for high-end gaming GPUs? i mean this would change everything. MacBook Air as a high-end gaming system, or a mac mini!. So my question to sum it up: Why isn't this possible for high end GPUs yet? am i missing something? is it not possible through the thunderbolt yet? Hope i wont get flame, i have tried searching for this very subject on google, but nobody seems to ask the same question as me. Have a nice weekend. Posted this in MacBook Pro forums, sorry if its in the wrong forum. edit: Drivers might be an issue, but bootcamp gaming will still be possible.
