I'm building my first gaming PC this winter, and I want to know if I should go with higher frequency RAM or stick with 1600Mhz. (The lower frequency ram is considerably cheaper, not that it matters.)

Does it improve gaming performance?
When is 2133mhz ram useful for?

I think I put it in the wrong thread, sorry.

It can boost performance, but not by a ton. Usually I only recommend high RAM freq for large business applications or professional work where it actually makes a big difference. 1-5% more FPS probably isn't worth paying double. I use 1866 because it was the same price as 1600 honestly.

Just make sure to get RAM with decent timings. 1866 Cas 11 is worse than 1600 Cas 9 I believe. Shoot for 1600 Cas 9 at the very least and maybe 1866 Cas 9 if you can find it for the same price (or just a few $ more) just make sure your motherboard supports the OC RAM profiles.

high speed ram only really comes out with any sort of effect on cpus without L3 cache or the igpu on an intel/amd cpu. For intel cpus generally speaking 1600 is as fast as the cpu will take advantage of in ivy bridge, while haswell shows some advantage up to 1866. AMD cpus don't have great L3 cache, so they always show some improvement from faster ram... if they can handle it... generally most FX and PhII amd cpus can't handle ram at that speed... apus however... not only don't they have L3 cache, but they have an igpu that is faster the faster the ram you're using. As a result (and in summery) unless you're building with an a10-xxxx or planning on using the igpu of a haswell cpu, there really isn't a point to ddr3 2133 ram.

Thanks, I did find some ram for a few dollars more (and it was from the same company too, which is crucial by the way) and I've decided to get 2133Mhz Ram.
