Hi, I wanted to dedicate a separate thread to this question, since I think it's a big enough topic of its own. 1. How much RAM is enough? Obviously the more the merrier, but after a point it gets too costly, and I'm sure there are diminishing returns. What do you think about 12 (6x2GB)? I will be doing HD video editing, Audio recording in Pro Tools and Logic, and Photoshop processing. 2. Distribution - does distribution of RAM affect performance in any way? For example, is having 6 slots filled in with 1 GB ram sticks, and the other 2 filled with 3 GB sticks a good idea? Or is it better to distribute them evenly? Do certain slots get preference? Thanks!!
