If you dont turn off your comp and leave your browser (or browsers) open, RAM gets om nom'd harder than a lone dick at a horny slut p8rty
As price isnt a problem 32gb seems like a good idea, I also agree SSD would be nice but definitely far from a must have.
This.
Also, you can't change last year so forget about it, just focus on making the most of this year.
You're far from unsalvageable, you just need to be willing to put in the time and effort to commit fully and really push yourself
Good luck
I played the release version for ~70 hours (PC) with the only problem of any kind I encountered that the texture of the trees in the background fucked up and this was fixed with a restart.
No quest bugs whatsoever, though I haven't done the main story ones.
