Also the Core Duo iMacs are not more powerful than the G5's. The Core Duo iMacs were seriously prone to issues like this because they're RAM-starved and CPU-starved. The Core Duo was just not a very good CPU, the Core 2 Duo was enormously better. If you can scare up a Core 2 Duo system and feed it sufficient RAM, I'll bet it runs a lot better. An actual new iMac would run rings around the G5 system, taunting it mercilessly :-) The first gen Intel macs kicked G4's asses, but not the dual G5s. The bus speed is a third faster for the G5, the cache is smaller but you've got over twice the RAM, plus the clock speed is faster. However the main culprit here is the RAM. My old Core Duo iMac would grind to a complete halt for 5 minutes at a time bringing up a Windows VM if ANYTHING else was running, and most of it was due to the skimpy RAM. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
