The reason im asking is because the dual-athlon set-ups gave barely an increase in gaming performance when compared to a single processor rig. Obviously the Opteron is a completely different architecture to the Athlon, so as i understand it does that mean adding a second opteron chip will give a a full 2x performance in all CPU activities, gaming or otherwise? If im completely wrong feel free to provide me with a correction, as i'm sure you all will! 😀:beer:

How will a Dual Opteron rig perform in gaming, 2x the performance?

The performance increase would be better v. a dual Athlon system as dual Opteron would have twice the memory bandwidth of single Opteron. However, a single-threaded app would only have access to memory bandwidth of the first processor + about 500MB/sec due to the fact that the second bank is only accessible to the first processor over the HT bus.
Long story short, dual Opteron would have ~15% more memory bandwidth in single-threaded apps.

hmmmmm, gaming while video encoding.... [looks at bank balance] pipedream for the time being

Correct IF you're running a multi-threaded app. One of the consequences of having the memory controller located on the processor is that you're limited by the FSB for cross-controller memory access.
