seen on nvidia homepage is this I guess this is the release of the nvidia 4mx. Mac first of course since you can already buy the new powermac w/ nvidia 4. This looks very nice and to clear the entire mx or not thing up. The MX series is the lowend consumer grade chip which satifys most every one in the wintel world and some macusers. the quadro/ non-mx line is the high end for video developers and the like which need the extra power. So the Nvidia 3 is faster then the nvidia 4MX or equal where the 4MX is faster then the 3mx.
