Actually, it isn't anywhere near as fast or as capable:
- He's running 4 cores at 2.4GHz. In comparison, a base line Mac Pro has 8 cores at 2.8GHz.
- His video card is a 8600GTS, which is less than half the speed of the 8800GT offered by Apple.
- His DVD drive is a read only. All Mac Pros come with the Superdrive, which has all modes of Write available to it.
- His Mobo has only 2 PCI-E slots 16x, same as the Mac Pro, but for the other PCI-E slots he has two 1x stubby slots vs the Mac Pro's two 4x full length slots.
- He has one Firewire 400 port, vs the Mac Pro that has 2 Firewire 400's and 2 Firewire 800's.
- He has one Gigabit Lan port, vs the Mac Pro's 2
- His mobo supports up to 8GBs memory, vs the Mac Pro's 32GBs.
- His FSB is 1066MHz vs the Mac Pro's 1600MHz
I hate to say it, but that is no where near as speced out as a Mac Pro...
