For CPUs yes...
but the RAM slots are wack, six 1GB sticks of RAM is wack, no USB3 would be wack, for the money the hard drives should be closer to the largest available, the video card options are wack... the CPU options (at least as priced) were a little wack...
USB3.0 is not even the standard yet.... remember how long took to USB2.0 to make it into apple products.... and if u have a mac pro ... then there's always a PCIe expansion card for that
