My preliminary findings so far (haven't installed the Rift yet)
Did some benchmarks with the i7-2600K, 16GB DDR3 RAM, Sata SSD and the GTX1080 (slightly OC'ed) before upgrading.
Passmark's results:
- Rating: 4641,4
- CPU 8490,6
- 2D Graphics : 790,3
- 3D Graphics : 12809,5
- Memory : 2402,2
- Disk: 5240,9
VRMark Orange Room: 7672
3DMark: 6047
Then changed to an i7-9700K with 32GB 3200Mhz RAM, Z390 motherbord, 2x NVMe Evo 970 500GB and the same GTX1080 (not OC'ed this time)
Passmark's results:
- Rating: 8250,6
- CPU 19046,8
- 2D Graphics : 1147,1
- 3D Graphics : 14303
- Memory : 3830,8
- Disk: 25916,9
VRMark Orange Room: 12442
3DMark: 7732
The overall performance increase is quite visible (doubling of the CPU score, 1,5x 2D increase, almost no increase in the 3D area according to Passmark) and a 4,5x increase in diskperformance.
VRMark, which simulates VR (as the name suggests) shows an 1,6x increase.
So...my guess is that the card is almost stretched out concerning it's performance now. Maybe a OC will give me a bit more.
Next: get the Rift installed and do some DCS :) As far as I've read, I might get some visual enhancements at a higher level than before...with the exception of MSAA since that'll kill DCS in VR.
