I know we've had 10-boxing tests on i7-2600k CPUs with various other bits attached but I don't think anyone has done any side-by-side testing on otherwise identical hardware/setups. The best we've got is anecdotes regarding GPUs on various platforms, with the only demonstrable variable being VRAM size (where more = better).

You might PM Doz3rr and see how he likes his and which model he bought. http://www.dual-boxing.com/threads/4...to-x6-was-nice
