    Would you see much improvement from the increased speed?

    No. I'm still checking out reviews for DDR4, and still noting with bafflement that there is no significant advantage for any speed rating in the family. In some aspects, there is no performance difference at all. People are paying silly amounts of money over the odds for imperceptible gains, if any.

    When buying DDR4, just look for price vs the CAS latency and get your best balance - ignore the MHz rating. Also, don't bother buying more than 32GB. I'm quite a heavy resource user, due to making big multi-channel 24-bit audio projects as soundtrack to video (I need video and audio running simultaneously for this). I could be wrong about this, but I have never yet seen a PC software operation that will demand resources above those that a 32GB system can provide. If all you're doing is running some apps and playing games, you definitely don't need to put 64GB in your system.

    To add to the above, I have only recently seen one or two specific games barely go over the 8GB mark (watch dogs 2 for example), so even 16GB should be sufficient for a couple of years I would say.

    I do have a similar question though, is there much performance increase from say DDR3 at 1600/1866 to a highly clocked DDR4? (I am not asking in regards to a straight upgrade as I know they would require different motherboards, but putting that aside...) I have noticed that there seems to be some discussion in relation to GTAV where people think faster ram is making a difference for example, is this completely wrong, a funny quirk or a sign of the future?

    If you check out Linus's YouTube Channel there are a few good videos on this topic, lots of testing and proof that upping the RAM speed (or size beyond 16Gb for games) makes hardly any difference at all.

    Above 2400 is useless if you are just gaming...let alone getting a board that supports those high numbers

    To illustrate the relationship between memory bandwidth and processor performance, we re-ran all of our gaming benchmarks with the Core i5 7600K running at stock clocks and overclocked to 4.8GHz. We ran each title with our Corsair modules running at 2133MHz, 2400MHz and their max rated 3000MHz. The results can be remarkable. An overclocked i5 running at 4.8GHz with 2133MHz modules can be beaten in some scenarios by the i5 running at stock speeds with 3000MHz DDR4. And let's remember that 3000MHz DDR4 is no longer the limit - overclocked modules are now hitting 4200MHz.

    It's not that speed (MHz) doesn't make a difference it's the relationship between CL and speed, i think there's some maths that explains it but ICBA to look it up, basically as speeds increase real world latency decreases.

    Only one of those tests had any relevance to the end user. The only games showing improvement had >100fps1, so an imperceptible gain. The only test with an fps in the range where improvements are useful was AoS, and that showed a marginally higher fps with the 4.8GHz CPU/2.1GHz ram combo than the stock CPU/3GHz ram combo. Looking on scan I can't see much of a price difference between 2.1GHz & 3GHz2, so there isn't much reason to not get 3GHz ram, but don't expect any noticeable difference

    1: if anyone quibbles about the witcher I'll scream
    2: 2.1GHz vs 3GHz - £4 difference

    You edit and make videos with sound?

    How important is it to have error correcting ram in your system and do you use any?

    Does having 6 cores in your cpu make a significant difference in performance to if you had 4 cores?

    If you are genuinely interested then look at Linus's YouTube channel, there are many extensive videos comparing different processors and how they perform under multi-threaded / single tasks.
