I've recently settled with Worker's Comp insurance for an accident that has disabled me. For the 1st time in my life I can afford a Mac Pro, but I don't want to just waste money. I would like to buy a computer I can use for 5 or 6 years. My main need is converting video files to h.264 for my TV and iPod (2 or 3 videos a day). This is what I am currently faced with (click thumbnail): This conversion has been running for 40 mins and there's 360+ left to go on my Mac Mini 1.5 G4 (overclocked 1.25 G4) (This is for a video of 49 mins) Will I notice a huge improvement in speed of the Mac Pro Quad Core 2.66 over the iMac 2.8 for encoding h.264, or ripping DVD's, for TV and iPods? I don't play any games, nor will I use Windows. Sorry if this has been asked a hundred times already. I looked through the forums, but didn't see this exact scenario addressed.
