The iMac is starting to show its age. It's processor hasn't seen an improvement in months. The video card is uncapable of performing on par with today's standards. So, what will the next revision of the iMac bring? Here are a few key items that we'll probably see in the next revision: Faster Processors We'll probably see something in the 900-1100MHz range. Although a slight improvement, it's improvement. Also rumored is the move to a 133MHz system bus, and hopefuls are wishing for a L3 cache. Video Card Upgrade With the Radeon 9000 recently released, the iMac could easily see an upgrade in the graphics department. The Radeon 9000 is the best budget video card in existence. Display Changes The 17" display might be moved into a second iMac, giving us only one 15" option and two 17" options. The rumored phasing out of the 15" LCD has significant evidence to support itself.
