Some of the problem the question caused a differance in approaches to the question based on parts of the whole question.  
The question ended up with people quibbling over the different aspects of a complex question.

For future referance limiting your question to single things, could keep the question from being observed 2 different ways, 3 If you account for the price thing added.  
Does ram CAS RAS refresh rates make that much speed differance. A) in ram speed B) in overall computer speed.  
Is much more memory beneficial to my needs assuming these programs.  
Is low latency memory worth the extra money (opinion)

It was the Duality of the question.  "More memory is better , because the way the system utalises it."  "Faster memory is faster, the value of such to be determined by the buyer."

I thought the question was ok, it wasn't until it was answered that you could see the train wreck it created. I also thought that the answers did not deserve to be downvoted.  Overall you did get what you came for.

If at any time you could break your question into single items, facting out one item would endure time, be more useful for others, and would not be observed different ways.

Knowing some data on how timing and speed settings effects ram, then knowing if much more ram is useful to your scenario, would have still given you enough data to decide.
