*sigh* tissue paper
this is nehalem architecture. they solved the memory speed handicap. which means that it doesn't need fast memory like the core 2 duo era did.
buy 1866 mhz cl9 in the capacity that you need. DO NOT buy DDR4. only DDR3. honestly, even 1333 works.
basically, each memory tier is more expensive nowadays, but ANY grade of memory works the same. so generally speaking, memory prices haven't risen.
That is NOT TRUE..
when the cpu has more memory bandwidth.. EVERYTHING will on average run faster..
The little bits of time savings here/there will add up because, the computer is something we're chained to..
2400mhz provides 25-35% more bandwidth depending on how well you've tweaked it.
you're trying to tell me that the CPU runs 10GB/s of data? AKA, it transcodes HD lord of the rings EVERY SINGLE SECOND?
sorry you're not an engineer
here's a tissue for your issue?

It doesn't need to run 10GB of data..
WHile it is true, that whatever time the machine may save by running with faster ram is easily used up when you waste your time watching a tv show.
That does not alter the FACT.... that EVERYTHING the computer is doing is done faster..
When you benchmark something, it is done given an arbitrary start and stop period..
That is NOT how real life works.. Real life has no such periods.. and the Speed bonus is ON GOING..
Look at it this way.. You get +2% research bonus in Civ, that's ONGOING forever, that 2% will count..
Benchmarking a certain task for an hour, and saying that only put out 1 frame more per second.. is NOT the realism we deal with..
You fundamentally misunderstand Passive-attributes..
if you look at the benchmark.. lets just say it saves you 2 second from modifying a jpeg..
what happens when you do 100s of jpegs
lets say it saves you 10 minutes on a video encode..
what happens when you do 100s of video encodes..
now, WHAT is real-life computer use... it's 8 hours a day.. add up all the time savings.. then keep multiplying because no body stops to breath these days..
It's computer 24/7, time savings..
