Yes, but note that the P1 workstations are pretty much the same as the X1 Extreme series (but with Nvidia's Quadro "workstation" GPUs rather than Nvidia's "customer" GPUs.)
nvidia have always been a hassle to use.
If I had known that when I was picking out an X1 for work, I would have pushed a P1 with no dedicated GPU instead.
(Also, what pentium166 says.)
