My mate tells me if you configure the new Mac Pro to the highest spec on the site it comes to: £8259.03

This covers the following droolworthy specs:
* Two 3GHz Dual-Core Intel Xeon
* 16GB (8 x 2GB) RAM
* NVIDIA Quadro FX 4500 512MB, Stereo 3D (2 x dual-link DVI)
* 500GB 7200-rpm Serial ATA 3Gb/s
* 500GB 7200-rpm Serial ATA 3Gb/s
* 500GB 7200-rpm Serial ATA 3Gb/s
* 500GB 7200-rpm Serial ATA 3Gb/s
* 2 x SuperDrives
* Both Bluetooth 2.0+EDR and AirPort Extreme
* Five USB ports
* Two FireWire 400

Apparently £3840 of that is the 15GB extra RAM. Hmm...
