> putting the graphics card off-motherboard. Honestly its still not very good at that. Its 'doable' but for intensive applications, it can't come even close to internal connections. For comparison a PCI Express 3.0 x16 link provides 16GB/sec in each direction to main to memory. Thunderbolt '1.0' only offers 1.25GB/sec in each direction per channel, use both channels and you get to 2.5GB/sec putting you in the neighborhood of the old AGP x8 protocol in terms of total bandwidth. Double it for 'thunderbolt 2.0' and its still only 5.0GB/sec. And then there is latency....
