That is an edge case. You are talking about 144Hz, 1080p, gaming. That's a lot of qualifiers there buddy. Do you really call a 10% win in low resolution gaming a "win"?:

I couldn't laugh more at how stupid a statement that is. It takes Intel twice as much money and more power usage to make a CPU 10-20% more powerful than the 2700X - and that's just at the very top. Once you go below the 2700X, AMD blows everything out of the water in both performance and efficiency.
This is before we even talk about HEDT and Server chips (The true halo products) where AMD is making $1800 HEDT chips that destroy $10,000 Xeons.
