Yes I am testing with the 5960X first. I will have benchmarks at 3.5GHz and looks like 4.5GHz. The Audio testing was done with both of those and the performance difference was big so far on the audio. Still to early to tell on video but so far definitely an improvement already even at 3.5Ghz. BTW even 3.5GHz plays back 4K R3D 4 layer full resolution preview like butter with less than 50% cpu load.
