I have a G4 PowerMAC, 450 MHZ. I want to upgrade it to run Virtual PC 7 so I can run some Windows applications. I was looking at the requirements for Virtual PC 7 which requires a CPU of at least 700 MHZ, (Native). On the box its states that accelerator cards are not supported. However, I talked to a couple salesmen at an Apple store and they told me that they have a Sonnet accelerator card installed on their own MACs and are both able to run Virtual PC 7 without any problems. Why does Microsoft claim that Virtual PC 7 is not supported with an accelerator card if the program works with this card?
