It's getting close to that time when we get our tax returns. I plan on using some of mine to purchase a 24" aluminum iMac. I'm torn between the 2.4mhz and the 2.8mhz models. Apple store shows a $250.00 price difference between the two models. Is it worthwhile spending the extra money to get the faster processor? The boost is not that significant but looking at 2 to 3 years down the line it may matter. I don't plan on doing any heavy video editing (some minor) and my primary usage will be Aperture, Photoshop, Lightroom, Final cut, web-surfing and World of Warcraft. Help me out guys. Will getting a 2.4mhz will have any serious impact on performance on any the above named software?
