Though doubting it is, as Apple claims, the fastest desktop computer in the world, Infoworld calls the Power Mac G5 “the ideal Mac.” It may not be the fastest in raw computing speed, but the reviewer says that “I/O throughput, especially memory performance, is infinitely more important than raw computing speed.” Infoworld also praises the G5’s design, “efficient and highly integrated system chip set,” and Mac OS X 10.3 (Panther) operating system.
