That sounds like a socket 604 (Intel) Xeon chip. Many Dell Precision workstations run Socket 604 Xeon processors. Examples include the 470, 650, and 670.
Yes, You can build a system around it, but it's not worth it.
Xeon systems are specialty things. After building half-a-dozen of them, I have learned to get a running system, complete with (several) processors, a motherboard, heatsinks, RAM, and an operating system.
Just figuring out the ranks of ECC RAM can drive You insane. Then, You learn that 95% of Microsoft's OS installation media will not work on Xeon-based systems.
I run many Socket 771 Xeon-based systems. These are Dell Precision 690 and T7400 models. They were super-fast in their day:
(1) 2x quad-core processors,
(2) Dozens of gigs of FB DIMMS (ECC DDR2,)
(3) Quad-Channel RAM.
The down sides to these (Dell Precision Socket 771) systems are:
(1) PCI-e 1.1 (which means SLOW video)
(2) FB DIMMs are really expensive
(3) Limited Windows 7/8 support. You have to get it installed somehow, then install Vista x64 drivers the newer x64 OSes.
Good luck, but (as I said) You are better off buying a running Dell Precision workstation rather than starting with a single chip.
