Okay, so I finally want to spring for a new Mac Pro. I don't want to go over 2600.00 USD, so I have two upgrade choices. I can get the graphics card upgrade, or the 2gig RAM upgrade. (wish i could get both) I am a graphic designer, using CS2 and stuido 8 most of the time. Should I upgrade RAM to 2 gig, or keep it at 1 and spring for the ATI card? I don't really play games but occassionally use Maya...
