Hey, after the disappointment with the MBP updates I am thinking of sinking some cash into my mac pro. I was originally gonna sell my 17" MBP and score a new laptop but I think I'm gonna stick with it. The cash that I've got kicking around will go on some new bits and pieces. This is what I'm planning; Extra 4gb of ram for the mac pro new video card for mac pro, ATI 3870? 4gb ram upgrade for the MBP new lens I mainly do a lot of aperture work on the mac pro, is the 3870 a decent enough card for this? will i see the benefit over the x1900 that came with the mac pro? are there any other cards that i should be considering?
