I am hunted by this problem for far too long and spent countless hours researching and trying to fix this with no solution. I went through 3 different graphic cards (ended up with a Nvidia GTX 285 for now) and also tried a MXO 2 mini as a replacement for our decklink multibridge pro. So it does not seem to be make a difference whether you use AJA, BM or other monitoring solutions.
It is horrible to sit in an intensive edit with a director next to you and be hunted by these flashes/crashes. The stuttering on our machine looks identical to the video shared by Dana Strom.
Working on an Imac or Macbook Pro is much more stable. I was asked by my client to either get a new machine (so I am looking at the i7 Imac with thunderbolt now) or he’d go somewhere else next time.
So I am wondering: Should I wait for FCP X before taking the plunge?
