After Effects performance comparison for 1080 Ti and Vega 64

I'm going to buy a new computer for After Effects. I've tested my ancient PC (i5-750 OC 4.1 GHz, GTX 1060 6GB, 20GB RAM, SSD 850 PRO) as they did in this article. Especially I'm very interested to know performance comparison for 1080 Ti and Vega 64 on Windows and on Mac. If you have these gpu cards It would be great if you can post your results of these tests here. My tests are below:

Cuda enabled, 32 bit, Caps Lock on, purged all memory before every test, (i7-6900k, 1080 from the article/My PC).

RAM Preview

5K - 52 sec; 2.89 (compare to 1080)

The People's Template - 682 sec; 1.97 (90% correct value: not enough ram for full preview)

Fiber Particles - 109 sec; 1.65

Render

5K - 67 sec; 2.91

The People's Template - 680 sec; 1.79

Fiber Particles - 111 sec; 1.56

The new $5,633 PC or nearly $10k Mac Pro is just from 1.56 to 2.91 times faster than mine. Actually I expected to see 10 times difference or more...
