Many games will perform much better with fast (and low latency) memory. Try google Fallout 4 memory benchmark for example
Pretty much all games with texture streaming performs way better with fast memory
60 Hz gamers should not care that much, but 120+ Hz gamers definitely should. It's almost always CPU and memory that is the bottleneck when chasing very high fps. It's here you'll see the benefit of CPU OC and high speed / low latency memory. Difference can be huge.
Don't get me wrong ,I'm not arguing that what you're saying isnt technically true, and I am by far no expert on this issue. But every video or benchmark graph I check out, shows an average variance of about 8 frames per second from 1600 MHz up to say 2400 MHz. Im not saying no improvement exists, it just seems to be limited from my searches.
And since OP is choosing between ram that has a price difference of $140 (the faster set is close to double the slower), it seems to me that wording the facts properly is important.
" The faster set of ram could yield higher frame rates in certain games, anywhere from 2 frames per second all the way up to 9 or 10 frames per second".
Seems more factual based on what ive found. But even if it was higher than 10fps, for me it wouldn't make a difference ,because paying twice the amount for slightly faster ram just wouldn't be worth it for me.
Depends on the game ofc. And here is a sample.
Yea, that matches the results I found. Hardly worth double the cost for 6 frames per second (in specific titles) to 9 out of 10 users. Even if every game ever made, performed 10 frames per second faster with faster ram, it still wouldn't be worth it (unless the cost was FAR less than what this thread is refering to) . In my opinion anyone who would argue it would be worth it ,is just someone trying to justify the fact that they got duped into paying more for "faster" ram.
