I've been on linux for well over a year now on my way to 2 years.
But I wanted a fix of good old Skyrim so I getto installed Windows and Skyrim mostly on a usb 2, 5 or 6 year old at least external drive.
My machine has 16G ram more than average I guess. The thing I found was once the game loaded and run it was as if I had the fastest SSD money could buy.
The secret is if you have ram games or software are cached and the storage speed is irelavant after the first load. Sometimes I would wonder why we drum faster media, when more memory is even faster again...
My ghetto Skyrim on a usb2 external drive loaded areas like they were stored on M.2 actually faster... Caching.
If your making a super gaming rig maybe add more memory !
Most gamers want enough memory and CPU for their GPU not to throttle because that is where most gamers put the money. I get the idea, there is no such thing as 'too much memory'. I am a bit of a memory whore myself and improving on load times is great. But how many games do really profit from it? Does it make a difference in gameplay? In most games it won't.
So if a "normal person" is building a gaming rig, memory has to be adequate. But when a "yacht with helipad owner" builds ... sorry, pays someone to build a system, then sure. Fuck it, DDR4 4000, 32GB Dimm x 8. "RAM? Is that good? What is the most expensive one? OK, I take a thousand. And make it look different than the poor people ones."
