Has >incompatibility with Virtual PC 5 been sorted? I had a G4/800 on loan for testing for a while. In MacBench 5.0 it scored 2053 in CPU and 1959 in FPU. I do not have scores for a G4/450 card to which to compare. Faster CPUs also improve disk and video performance a little. Compared to a G3/315 with 512K cache disk performance was about the same actually. I guess the G3/315 is sufficient to open any disk bottlenecks. MacBench Graphics using a Formac Proformance III card was 3232 with the G4/800 and 1190 with the G3/314. Publishing Graphics was 2203 and 1609 respectively.
