I am no expert but have been trying to work out the fastest or best CPU that I can run on this system.
So far I have concluded a Opteron 156 to be the fastest. But would a slower duel core be better.
Current system:

AMD Opteron 154 San Diago 2.8GB CPU.
Foxconn NF4K8AC-8EKRS Socket 939 Motherboard.
2048MB Geil Ultra-X nForce4 PC3200 DDR400 CL2 Dual Channel Memory.
450 Watt Power Supply.
DVD Rom Combo.
GeForce 7950 GT Graphics.
Seagate Baracuda 160GB Sata2 Hard Drive partitioned 20/20/120
Dual booted with Vista Home Premium & XP Pro sp2

I think you'll have to replace the mobo and CPU, if u want dual core

And probably the ram, since it wont be compatible with a mobo that supports dual core

It looks like there are Opterons that support dual core, but theyre 940 pin not 939 pin

Rocky, what are you mainly wanting to do, boost your rig for games or something else?

It gets used mainly for driving & flight sim.
It goes quite well as such, was just wondering what the best CPU would be.

The problem is its an obsolete socket, you may find a store with a 939 X2 4800+ or something (old stock).

I would DEFINATELY bump your GPU before the CPU, the bottleneck is going to be the 7950 not your CPU in most games, in certain flight sims it may be both, but a better GPU will help.

I would grab maybe a 9600Gt for $240ish +, you can use it on your next platform as well being PCIE, beats buying a obsolete processor that probably won't help much.
