It is definitely better when they still have a proper versioning system and it is unfortunate that many handle it poorly even outside of subscription programs.
I can see how subscriptions are very helpful to handling expenses on the business side especially for any program that operates in a way that security updates are important. But far too many companies have set the price way to high and hid it with a short time so it looks cheap. If yearly was the default length and was reasonably priced then I would be fine with them but $5 a month for a lot of things that could easily be $5 a year is too much.
If they did that then they likely would end up with melted 8 pin connectors as that derating is a protection against one pin being overused due to small expected differences in resistance on each pin
depends on if you are commonly cpu limited or not. If you are having performance drops from the cpu not keeping up then go with 16gb 3600Mhz to get a little more performance. If you never are being cpu limited then the extra ram would be better as it will be used for caching to help load times and reduce the chance of fps dips related to loading assets
It depends on the application used as some show cached as used and some don’t. But it is being more common to not show cached as used.
