Dual Xeon vs Single Xeon?

I recently picked up a Dell Precision Workstation 450 from my work. Yes I am aware of the age. I still love to mess with these machines though.

Anyway, currently it has a Xeon 2.66Ghz 512kb 533FSB. This is based of the NetBurst arch. I think. I know it isn't to fantastic and will generate a lot of heat. It has a 2nd CPU slot free which I would like to throw another 2.66Ghz Xeon in. Both CPUs have HT so it would look almost like a Quad Core(I am aware it won't act like one though)

Does anyone know the performance differences? Will a second processor increase performance?

This desktop also has a PCIX, 2xPCI, AGP X8. I am probably gonna grab a Radeon X850XT 256mb GDDR3. How would gaming be on this system? (Currently I have a GeForce 2MX inside of it :p)

I would mostly play Battlefront 1(plays perfectly on a Pentium M1.6, Radeon 9000 for me), Fallout 3 maybe, Call of Duty 4(long shot but still curious), Advent Rising, Wolfenstein Return to Castle, etc. Most games aren't new. Maybe CS:Go? :p

The CPUs are pretty cheap so I guess it wouldn't hurt.

Im also planning to probably use this for browsing. Which it should handle perfectly, no? And multitasking as well with old applications such as WorldCraft 3D(Map editor for Quake) and Valve Hammer Editor. Maybe even some Photoshop, but hey, if a GMA 950 can do everything I need. I'm pretty sure a X850XT could do it too. Anyone got any GPU recommendations?(I love Nvidia too, jus wouldn't be sure which to pick)
