Good Afternoon

My current computer is a Dell Precision 470 workstation.   Its motherboard is a OP7996 and is currently running two Intel Xeon (Nocona) 2.8 GHz cpu's  with 604 mPGA sockets.  Is this mobo capable of running Intel Xeon 2.8 Ghz DualCore processors?    Any help greatly appreciated as i have read so many conflicting reports on whether or not this upgrade is possible.

Thanks.:emotion-1:
