The dual core processors aren't great for gaming due to the overclocking limit, single cores overclock much higher. So your x1900 will be bottlenecked pretty good. I would recommend the opteron 170 or 175 and overclock it to the 2.8+ marks if you can...that will be your best bet unless you want to go with a single core cpu.
I've heard that dual core AMD processors actually OC quite well. I reccomend an Opteron Denmark 165 over all of the current dual core processors out there. It costs about the same, if not less than an x2 3800, yet has 2 times the cache, and will get to 2.8Ghz + with mid range air cooling.
