I noticed the new 27" comes w/ 2 TB ports. Anyone know if that means it will support 2 ext. monitors plus the iMac monitor? The top line has 1GB VRAM so should be enough on that end.
Unless Apple has limited it somehow, it should since the GPUs are capable of running up to 6 displays at the same time. TB supports daisy-chaning as well so in theory, you should be able to drive up to four ≤1920x1200 monitors or two up to 2560x1600 monitors (bandwidth gets too high with more 30" monitors).
