tried today - couldnt get it to work with the x1900 inside jan08 macpro. ( there are 2 graphics card power connectors inside the machine )
will hunt around see if i missed something.
the entire range of graphics cards just changed - have to see what happens in the next month.
8800 isnt available yet. listed as 5-7 weeks delivery on US applestore from today
I have 2 x xt2600 in my mac pro.
