Zactly The Mac For Your Jobs
IMHO Definitely. With the Quad each process you describe will run slower and/or flat out bog down the Mac so you can't even word process without waiting for characters to appear. I know this 'cause I already have this happening to me a lot on the Quad G5.If I was running upcomming Leopard OSX, a few osx apps, the full upcoming CS3 Suite (not necessarily Batch Processing), have After Effects rendering a 30 minute clip in the background, downloading *legal torrents, watching internet tv (muted), while burning a DVD and listening to music..
That keeping in mind I won't necessariy be rendering-multiple scenes, while encoding, batch processing with a multiple of applications while running SETI@home.... yet
Would that kind of Multi-tasking benefit through Multi-threading on the Octobot's 8-Cores..
Or slighly / not significant enough to warrant Going Octo over Quad..
