Hi all! I´m new on this forum and I´ve been a Mac user for the past 10 years. At the moment I´m working on a G4 Digital Audio 733 MHz and I´m thinking about a processor upgrade to make it faster with a Mercury Extreme upgrade card (http://eshop.macsales.com/Catalog_Item.cfm?ID=5860&Item=OWCME41400L2D). The guys in my Macstore dont sell and dont recommend those upgrades Does anyone have experiences with that or any suggestions? I wanna run Nuendo 2.0 and Logic 6.x mainly. All the best WOLFeen Ps: I have a G3 also, dunno if upgrading this one would make any sense?
