Go to unsanity.com and download their free haxie called Cee Pee You. When installed, it puts another item on the menu bar showing the CPU workload - in percent of capacity. On a dual machine, two numbers appear. ALL cocoa and carbon applications -- which by now is all apps of any consequence, the best having been carbonized for a couple of years now -- work with the Mac OS to distribute their CPU demands. I have yet to see one of the CPUs idle while the other one is working. The numbers move around and often bounce back and forth as the workload is distributed. Dual processors working in beautiful cooperation with the robustly stable and fluid Mac OS -- it gives me goosebumps just thinking about it. My 2.5 Ghz DP liquid-cooled Mac G5 tower simply walks away from my 3.6 GHz SP Pentium Dell in real world operation. It's hands down faster ...and it's quieter, too - no hype, just a fact. ------------------------------------------------- Ronald Woodland -- St. George, Utah 84770 ------------------------------------------------- This email is a natural human product.

My dual 1.42 PowerMac will mop up the floor pretty badly with an iMac G5. If you're looking at a G5, most definitely get one with 2 processors. The PowerPC 970 was designed from the ground up for SMP, and standalone G5's are not good performers. It works on the principal of instead of increasing the performance of desktop and server systems by using a few narrow pipelined, very high clockspeed, high power cpu's, IBM would rather see multiple, slower but wider, lower power cpu's ganged together via very high-bandwidth connections. This, incidentally, is also the philosophy behind IBM's Cell processor. -- Chris
