Would RAM speed matter for the GTX 1080ti?

[EnterRoundabout]

So I'm planning to purchase a GTX 1080ti this end of July and I've been wondering if my RAM sticks (16GB, 1866mhz) are enough to not cause FPS drops/bottlenecking. My system is currently rocking an i7 4790k OC'ed to 4.5GHz and just sold my GTX 980. Not planning to let go of my Z97 build since there's no point on upgrading to Kaby Lake atm.

Should be fine. But in some cases it would help a lot. Core is king, and at stock on my rig it runs 4.2GHz CPU core clock, 2133MHz 15-15-15-36 DDR4, which is probably about 20% or so faster than what you have, but your OC would make it faster than mine at stock for gaming most likely. But it makes such a tiny difference in most cases it is almost negligible. Only game I know of where Memory speed matters much is Fallout 4.

Going from 2133MHz 15-15-15-36 to 3200MHz 16-18-18-36 with XMP only give me like 2-3 more fps in most cases and up to 10 on Fallout 4. So it only really matters in a few cases. But core is king and your CPU should be more than capable of allowing a 1080 Ti to reach its full potential in the vast majority of cases.
