Dual channel DDR3 vs tri-channel DDR3.

While what gurusan said is correct I think more detail can be added.
In Real-World Gaming the Bottle-Neck is currently the GPU and the added bandwidth of Tri-Channel won't amount to much extra benefit . . . . however once the GPU is removed as a bottleneck the extra Tri-Channel bandwidth will go to work!
The only way to test this is either time travel a year into the future, nab a GPU and bring it back to August 2009 to do some testing, if Time Travel is not an option then you can do some testing by simply dropping the graphics options to Medium/Low and reduce the resolution to 1024x768 or 800x600 and do some testing.
I've observed up to an extra 50 fps by maximising Memory/FSB bandwidth in titles such as Crysis using this method.
Outside of gaming I noticed a pretty decent Speed-Up from boosting Memory Bandwidth in predictive tasks such as Video-Encoding etc
So its horses for courses, if somebody is gonna have a two/three way Crossfire/SLI set-up then Tri-Channel memory is obviously gonna be a good thing as it would be for a Multi-Media producer who is literally encoding/rendering day in day out, for most of us the benefit is not tangible . . .unless your a benchmarker!
