I am deeply disappointed that the new base model 8-core mac pro has had it's clock frequency reduced by 20%. I'm even more disappointed that the price went up 18%, or $500. I know that the Nehalem processors are more efficient etc, but many apps use only one core and therefore rely solely on the CPU speed. You would think that is 2009, you would be able to get a new Mac Pro in the 3GHz range for less than 3K? In have been waiting eagerly for the new Mac Pros to arrive and I am ready to buy. But with these prices I just feel cheated. Charging 6K for a 2.93GHz 8-core Mac Pro just seems preposterous, Especially since last year's top model was $4399 and topped out at 3.2GHz. What makes these prices even more baffling is what happens to the price when you step up from a 4-core machine to an 8-core. The 4-core 2.66 MP costs $2649 (with 6GB of RAM) and the 8-core costs $4699. That's an additional $2050 for a second CPU, or a 78% increase in price. If each CPU costs $2050, then the rest of the computer is only worth $599. That doesn't make any sense! And if you compare the 2.93 MP, each CPU is $2700, and the rest of the computer only $499. It's mind-boggling. Does anyone know what the retail price of these CPUs will be? I doubt that Apple is paying $2050 and $2700 respectively for these babies.
