Hi, I'm about to buy an 4870 for my 2006 Macpro. I like to keep my x1900 as well so I can use 3 monitors. However, is there enough power connectors to do this? As far as I know the 4870 would use 2 and the 1900 would use 1. If there is not enough, is there any other way to do this? Can I take power from the second drive bay for example?
