Scroll down and you'll see a 10 game benchmark average. The i7 8700k is only 9% faster.It's very late. When I wake I will look for the charts that show software benches.
"All the results are for CPUs running at stock speeds"
Which means those benches are skewed in amd's favor due to their poor headroom
a 5ghz 8700k is a whole other beast

Note that, per the first page, both CPUs were OC'd: i7 to 5.0GHz, & the R7 to 4.2GHz...& despite its ~20% advantage in clock speed, the OC'd i7 only managed ~13%
average performance edge at 720p, 9% at 1080p... & only 4% faster at 1440p.
And the results themselves have some outliers on the data:
■ Not sure why, but they claim that Starcraft II only uses a single thread...although it would explain why you'd get 20-30% better performance from the CPU that's running 20% faster. However, it appears there might be some sort of limitation in the game engine itself -- as it boggles the mind how, with these 2 top-of-the-line CPUs paired with a GTX 1080TI, you'd have identical average & 1% FPS rates for each combination at 720p, 1080p & 1440p.
■ The average FPS rates were so ridiculously high on both CPUs (both well over 500+ FPS at all resolutions) that they used the 1% minimum figures.
■ Although Overwatch looks like it has a huge FPS gap in performance, remember that both were hitting well over 200 FPS averages (& close to that on the 1% mins) at 720p & 1080p. When your FPS is that high, even a 20FPS margin isn't going to make that much of a difference.
■ Pretty much across the board, once you hit 1440p you're much more limited by the GPU than either CPU, as their performances become nearly identical.
■
The OP, however, is currently using a GTX 970...which, being roughly comparable to the current GTX 1060, is going to see much more of a
GPU-related limitation at 1080p than Techspot did in their testing.
Long story short: i7-8700K's game performance is measurably greater than the R7 2700X, but since the OP isn't going to be strictly gaming he's probably better off picking the Ryzen instead of the i7.
