I am not a scientist, A/V professional or otherwise a number cruncher. I am a man who craves speed and I like to know that I have the fastest machine currently available. I have been dreaming of a Mc Pro for the last 7 years. What I do with my computer: 1. Use it as a server (15 users, light use - not currently central, but could become so); 2. Occasionally (once or twice a week for several hours at a time) use it for Photoshop and other CS5 programs; 3. Occasionally (once or twice a week for several hours at a time) rip CDs and DVDs with Handbrake; 4. Virtual Machines (all day, every day); 5. 10-15 Business productivity applications all day every day (including Adobe Acrobat, which seems to inordinately drain resources). My goal: to never see a spinning beach ball ever again. Right now, I have an X25-E, 8 GB ram and 2.66 Duo Core MBP. I see the spinning beach ball relatively often. My RAM usage is high (yesterday I had less than 500MB free for a significant period of time), but I might only see an 80-100% CPU spike once a day. I think I know the answer to my question, but is a 6 - Core just a stupid waste power here?
