I have a early 2009 octo mac pro. Right now I have 2x gt120 cards, and no other expansion cards, and I am driving four displays (two DP displays and two DVI displays). I'd like to drive more displays. If I buy that new radeon 7950 and put it in my double-height slot 1, then put my two gt120 cards in slots 2 and 3 ... then I could drive: - 4 existing displays with my 2x gt120 - 4 more displays (2 DP, 1 DVI, 1 HDMI) with the radeon 7950 *and* I'd still have one remaining unused expansion slot ... right ?? Any reason this wouldn't work ?
