Dear Jitter gurus,
We’re putting together a permanent 5+ HD screen installation with Jitter. We’re mostly putting photos on videoplanes and manipulating them. Plan A was to use a new Mac Pro which we were lead to believe could accommodate 2 x ATI 5870s with power from the HD bays or external power, but this seems not possible (works great with a 5770). External power needs to be linked to the mother board (which is a bear to get at) and there’s not enough internal power. So we’re looking into some alternatives but are unsure of some specs, particularly if we go Alienware. Can Jitter take advantage of the dual GPUs of the ATI 5970 and/or Crossfire? Here’s what we’re considering:
Plan A: stay with the Mac Pro, take it apart to get at the motherboard (we’re musicians I warn you) and try to power a second ATI 5870 by some yet unknown means.
Plan B: get a CUBIX GPU-Xpander Desktop 2 or similar put one 5870 in that. Expensive, but we could have 2 x 5870s for the screens and run the control screen off an x8 slot with a 5770.
Plan C: go Alienware and stuff a PC with a couple of ATI 5970s. If, however, Jitter is not able to take advantage of Crossfire and/or dual GPU cards, this would only have the power of Plan B and be even more costly.
Any advice from those running any of the above much appreciated.
