The year is 2018: Ryzen & Ryzen 2 are released which are obviously the better choice, for a CPU budget upto ~$300, but this matter is widely discussed, so I'll just bring up the main factors, why AMD is the better choice:
1. All Ryzen & Ryzen 2 processors are overclockable.
2. The performance of Ryzen processors are better than Intels counter parts,
3. while being available at a lower price point!
4. AMD's said that the current AM4 socket will be held upon to 2020/22, all while having backwards compatibility for their Ryzen Chipsets. Meaning you won't have to upgrade you mobo every generation.
InkyBuisnessCheaper, yes. Better, no. Ryzen 2700x has 2 more cores than the comparable 8700k but each core is a lower clock speed and since most games can't use more than 4 cores at the maximum. While I would agree that ryzen is a better price to performance CPU than intel, it is not better period, given infinite money intel still comes out on top for gaming my a non-insignificant amount
