This is a huge and very important update for Apple and everyone who's been waiting for improvements to graphics performance. The new ATI X600 series 16X PCI-e card has twice the bandwidth of the current X8 AGP cards. Adding DDR2 RAM now also gives the new iMac support for up to 2.5GB RAM When you add in all the other features in this new configuration I have to give my resounding approval. The 17" WS model starting at $1199 (edu) with these features is the best bang for the buck ANYONE sells. This also gives us a fantastic preview of things to come in the PPC "Pipeline" Well done!
