David Nagel has a very interesting column in Creative Mac. Obviously replying to DV guru Charlie White’s ongoing tests of Intel-based PCs versus Macs when it comes to processing speed. White has shown that the fastest Intel machines render graphics and video (in applications like PhotoShop and After Effects) more quickly than the vaunted Mac. But as Nagel points out, the PC’s processor speed is not the key issue in creative work like that involved in producing digital video and high-end graphics. Work flow is more important, he argues, and in that sphere, the Mac continues to dominate.
