this was my first thought too... considering i had to hack my $6000 D700 mac pro into displaying 4k at 56hz instead of 60hz to avoid ridiculous noise/tearing on half the screen... I personally wouldn't touch 5k for another year at least. No way of knowing because it's not mentioned in the specs, but i'm guessing this new mac is limited to 30hz.
