Recently making the move of finally updating my early 2006/2007 Mac Pro. In addition to the 4 GBs of extra RAM I plan to slap into my Xeon 3Ghz Quad *making a total of 6GBs* I was thinking of making the plunge of getting the 4870 ATI upgrade (even though it is not officially supported for my Mac Pro). The issue I have at the moment, other than needing to upgrade Tiger to Leopard (then Snow Leopard) to take advantage of the video card is Mac OSX is the power cable to the card. From my understanding the card will need two connectors. Since my Mac Pro came with the dated ATI 1900 card I already have one black power connector. Does the Official ATI 4870 upgrade box include the necessary cables? Or will I have to look somewhere else for a cable to supply power to the video card? I am sure this something at face value seems like a non-issue - but I do not know if the same connector in later Mac Pros would be the same.
