I've been holding off on upgrading my Power Mac G4 to a faster processor since I heard that the MPC7457 would be coming out from Motorola (the newest cool running G4 chips that probably scale over 1.5GHz with 512k L2). I heard the rumors back in January and now almost half a year after most of the focus has been on the PPC970 (for obvious reasons ). Has anyone heard about these chips? Like are Powerlogix, Gigadesigns, and Sonnet going to be using these chips for their new upgrade cards? On a different topic, do you guys think that there will be PPC970 upgrade cards for current G4s?
