Apple updated its Mac Pro lineup today. The new base model starts at $2,999 and receives a bump to an Intel Xeon E5 6-core processor (up from four cores), two AMD FirePro D500 3GB video cards (up from two D300 2GB GPUs), and 16GB of RAM (up from 12GB). That's more or less $1,000 under Apple's previous pricing on this configuration. (For further comparison, we recently listed a refurb with these specs for $400 more.) It's available today.
An upgraded model has also been announced for $3,999, but it's currently unavailable for purchase. It steps up to an Intel Xeon E5 8-core processor and dual AMD FirePro D700 6GB GPUs.
