Totally not worth going mad with expensive ram then.
its bad amd put 3600C16 as a price/perf sweet spot when it has close performance as much cheaper 3200C14.
Where lower latency helps is when you have i/o that isnt VRAM and doesnt fit in cpu cache. How much it helps is then dependent on how much that i/o is a bottleneck, in most cases the benefits are very limited even to the point its not noticeable by a lot of people. Even in my own examples of lightning returns which is a kind of best case scenario for lower latency ram with its constant asset flushes, I wouldnt justify spending an extra fortune on ram for it, tweak your ram for it by all means but not spending the best parts of £100 on it.
If you have workloads where you get lots of bursty small in memory uncachable i/o at a high rate, thats the optimal scenario for lower latency memory access. There is not a whole lot of workloads covering that scenario.
Sadly that review is flawed like many others, done lazily as usual, there is no min frame rates to assess stutters on the game testing, which is odd as thats the area lower latency ram helps the most in games, its a tremendous oversight to then not test it.
