Can HP xw9400 Workstation use a GeForce GTX 560

[northernbard]

I bought an HP xw9400 Workstation with 2 EVGA geforce 8800gts Graphics cards in it.
My question is, can my Workstation take 2 GTX 560's( or any pcix16 2.0)
With 2 physical AMD Opteron 2427's (12 cores total) this machine just screams Game On ME!

The board (tyan s2519-e) has in order 2xPCI-e 1.0's, 1 PCI, 2PCI-e's, 2PCI-X's (7slots). But the PCI-es are auto switching to x8's. So you can use a GTX560 in slot 2 and 5 at x16 (@2.5Ghz) but this forces you to leave slot 1 and 4 unpopulated otherwise the pcie slots switch to x8 and it blocks slot 3 and 6 with the gpu fans. So it is possible but it takes up all but one PCIX slot.
