Hey. I am going to buy a new mac pro 8 core and wondered about the noise level of the NVIDIA GeForce GT 120 vs ATI Radeon HD 4870? I have a home-studio, so its important to keep it as quit as possible! I also want to start and score film music, and work with motion picture in DAW applications such as protools and Nuendo (if you understand what I mean) is a good graphic-card very important for this? have anyone any experience with this?
