there are people reporting that hd4000 is not capable of smooth system animations with TBD... and I am keen to believe, I have tested it in store and some animations with new air connected to TBD were not smooths - this is not the case with ati 6330m... it is pitty that quad core with ati like gpu does not exist.. why, only apple knows![]()
What is TBD? Thunderbolt Display?
I would think "choppiness" of the OS animations is super subjective, considering they aren't that great to begin with.
What I would be more concerned with is 1080p seamless playback. Thanks for the input both of you, in any case!
