I noticed Xeon E5-2666 V3 started showing up on Ebay selling between $300 and $350. What is great about this CPU is that it has same stepping as production variant. All cores running at 3.2Ghz 1-2 Cores running 3.5Ghz and 3rd core running 3.3-3.4 Ghz. I tested this one against i7 firstname.lastname@example.orgGhz, and it scored equal or better than 5930k in gaming. Benchies done with SLI 1080 in 2k and 4k resolution under Windows 7 x64. As far as pro work goes i7 5930k had no chance. This is amazing deal compared to retail i7 6950k, worth every penny in my book. It appears that once you pass 3.0Ghz clock speed with 10+ cores Xeons shit gets really serious.
