I have the opportunity of getting a MacPro with Quad 3.0GHZ processors, 3gig of ram, and 2 good geforce graphics card ( it can take a total of four! )
At the moment we use a G5 PowerMac 1.8dual core processor, 2gig of ram, 1 x graphics card

We are trying to spend our money in the wisest possible way to get the best render times that we can at the moment - does anybody have any other suggestions, or experience with using a MacPro
or generally any helpful comments

We are trying to do animation for video presentations, and want to get a reasonably fast workflow for producing 5 - 10 minute presentations ( some fully animated in Vue, [and blender!?] )

What's your experiance?
