replace one of the drives with a SLC SSD and use that as the boot disk. otherwise she may notice lag.
if she doesn't go for your setup; half the RAM, have a SLC SSD for bootup and at least a 2tb fast HDD for data, and one or two GPU's
also: only one dispay? and OEM K&M? tsk tsk.
At LEAST two displays, a Logitech DiNovo Edge Keyboard,
and a Sidewinder x8.
