GPU RAM test results and crypto-mining warning

From limited testing, my Nvidia GPU recommendations for the Develop module:
  • RAM is more important than speed for modern video cards. Example the 5GB P2200 is over 3 times as fast as the 4GB K1200 yet there was no difference in the develop module on a 4K monitor. They run out of GPU memory before they have a chance to use much of the processor 
  • 4GB is enough for up to 2K monitor so 2GB should be fine for FHD 
  • 8GB for 4K monitor, minimum 
  • some sliders don't yet use the GPU, Luminance noise reduction needs CORES CORES CORES, GPU on P2200 maxes at 1% as it does on the K1200 for this slider. 
  • thought about buying a M4000 (8GB) just for testing but looking forward to the next generation RTX4000, hoping they will up the RAM to an affordable 16GB 
  • my guess, on a 4K monitor, the slower M4000 would outperform the P2200 due to the video card memory of 8GB vs 5GB 
  • 5K monitor opinion (removed mine, just too slow), just doing the math, needs 75% more RAM than 4k so 14GB
  • 8K monitor opinion from reading some of the gaming tests, we'll need 32GB on the video card
Crypto-mining note: playing with Ethereum for fun and it consumed almost all the RAM on the video card so that Lightroom would hardly run until the crypto software discovered that it lacked sufficient video card resources and stopped running. Even after it stopped, took a couple minutes before Lightroom resumed normal running. 
 
Fun Fact: a year or so after I started developing software, there was an announcement that there was now 100MB (yes, megabytes) installed on all the computers in the world combined. Most computers had 2K, I worked on a supercomputer with 192K that run 40,000 double precision floating point operations per second; over 1 million times slower than the Xeon on my desktop.

No question. Just info.
