If you want to enjoy in overclocking better save money for X99. It's not so far if you think about Maximus VIII Extreme.
Who say Intel processors overclock worse and worse every year.
Average OC for i7-5960X is 1300-1500MHz... that's half of CPU frequency.
i7-5960X is really Intel's masterpiece... and only such designed processors deserve expensive motherboards over 250$.
I mean and i7-5930K and i7-5820K are excellent and you can cool them down without deliding but difference from stock speed and average
overclocking speed of i7-5960X is amazing.
