Look at these results carefully. http://www.barefeats.com/graphiX.htm The MX turns out to be one tough competitor. It edges out the Radeon in several tests, but falls behind in hi-quality gaming and 2D like I predicted. For you potential buyers out there, I suggest going with the Radeon. This article forgot to mention its stellar DVD playback capabilities and overclocking potential. Also note, the Radeon tested was a retail model, not the OEM version preinstalled in Mac desktops. The results should remain the same however. Only get a MX if you work a lot with 3D apps. I can't wait to see what a 733MHz G4 can do with these cards. BTW, check out the Photoshop benchmarks!! No wonder desktop publishers use Macs!!
