Well the advantage to that gigabyte board is 8 sata ports not the 6 most boards have(DFI is an exception but out of budget too).
They give you the bracket to send 2 of those as e-sata ports for those who want it.
There is not wifi or firewire(was not a concern for me).
Last off P35(from any company) chips are made for FSB 1333 so even a 1066 cpu will run at this speed with little to no voltage increase(3.0 easy you can get more if you want it, 400 seems easy as well[wont keep that in air in a 30c room]. i would not go farther then that with a 9x multi.).
