Yes, DDR3 is the lowest CAS latency and lasts ALOT longer.

Just like SSDs from 2010 have 100.000 writes per bit instead of below 10.000.

CPUs might even follow the same durability pattern but that remains to be seen.

Keep your old machines alive and backed up!

CAS latency is specified in cycles and clock rates are increasing, so despite the number getting bigger there's actually been a small improvement in latency with each generation.

Not for small amounts of data.

Bandwith increases, but if you only need a few bytes DDR3 is faster.

Also slower speed means less heat and longer life.

You can feel the speed advantage by just moving the mouse on a DDR3 PC...

		RAM latency doesn't affect mouse response in any perceptible way. The fastest gaming mice I know of run at 8000Hz, so that's 125000ns between samples, much bigger than any CAS latency. And most mice run substantially slower. Maybe your old PC used lower-latency GUI software, e.g. uncomposited Xorg instead of Wayland.

CAS latency doesn't matter so much as ns of total random-access latency and the raw clockspeed of the individual RAM cells. If you are accessing the same cell repeatedly, RAM hasn't gotten faster in years (around DDR2 IIRC).
