Apple's highly-anticipated (and most powerful) desktop machine, the Mac Pro, will finally go on sale tomorrow. It's the company's first Mac to come standard with dual workstation GPUs, and it's perfect if you're looking for a machine worthy of powering a new 4K display.

For $3,000, the lowest end Mac Pro comes with a 3.7GHz quad-core Xeon E5 processor, 12GB of 1866MHz DDR3 DRAM, a 256GB solid-state drive (with read/write speeds of up to 1 and 1.2 GB/second), and dual FirePro D300 GPUs, each armed with 2GB of video RAM. There are a total of six Thunderbolt 2 ports that can transport data at up to 20 GB per second. You can also connect up to three 4K displays or six Thunderbolt displays.

For a grand more, you get six 3.5GHz Xeon E5 cores, 16 GB of DDR3 ECC memory, D500 GPUs with 3 GB of video RAM, and the same 256GB solid-state drive. All that firepower gets packed in a shiny sci-fi looking black cylinder.

The new Mac Pro is available for order from Apple's website and retail stores starting tomorrow.
