As usual with the Intel-based Macs, Photoshop is a controversial test to run because Adobe hasn't converted the current version of Photoshop to run natively on Intel CPUs. This means it runs in Apple's Rosetta emulation mode and, as such, will be slow. It's valid because if you want to run Photoshop on an Intel-based Mac, that's what you have to deal with (Boot Camp aside) until Adobe comes out with an Intel-native Mac OS Creative Suite (due sometime next year). We didn't expect the Mac Pro to excel on this test, but to its credit it did better than we thought; the Mac Pro trailed the Windows test bed by only 45 seconds.

We think the most telling test in this suite is CineBench, which lets us test each system's video-rendering capability with one CPU thread, as well as with multiple, simultaneous CPU threads. On the single-threaded test, the Mac Pro won by a decent margin. But on the multiple CPUs test, the Mac Pro dominated, nearly tripling our Windows test bed's score. On the one hand, that's not a surprise, you'd expect a PC that supports up four concurrent threads to be faster than a PC that supports only two on a test that puts all available CPU cores to work. But what's important is that you can't currently buy a Core 2 Duo-based Windows PC that has four CPU cores. So this test lets us show that, all other things being equal, for programs that truly take advantage of multithreaded CPUs, the Mac Pro should give you a leg up over any consumer-level PC.

Our Quake 4 test is not exactly apples-to-apples because our Windows test bed used a GeForce 7600 GT 3D card, which has faster clock speeds than the Mac Pro's GeForce 7300 GT. We don't feel that bad about the disparity, though, because the next step up from Apple is a $350 ATI Radeon X1900 XT card. So unless you're serious about Mac gaming (chuckle), the 7300 GT is it for the Mac Pro on the lower end of the 3D scale, while your Windows 3D graphics card options are wide open. That said, Quake 4 on the Mac Pro is perfectly playable, even at the more demanding 1,600x1,200-resolution setting (albeit, less so), where it clocked 31.6 frames per second. We maintain that the Mac is not a good gaming platform, but the Mac Pro has so much raw CPU power that it can give you a nice boost.

Apple's service and support is still weak, especially for a high-end system such as the Mac Pro. The default plan gets you a year of hardware parts-and-labor coverage but only 90 days of phone support. For an additional $249, you can bump both the warranty and the phone support to three years via the AppleCare Protection Plan. Apple's forums continue to provide a wealth of product help, and Apple's own support page also has a decent amount of information.
