Don't overdo it. I think 1G RAM won't be 'standard' before 2000. If we take
Moores Law (twice as much every 18 months for storage space and processor
power) we're at 64MB and 300 MHz now, we'd be at about 128-196MB and 500-600
MHz at the end of 1999 - at MOST.

Win95a (the very first one) was quite happy with 16 MB.

One "advantage" of Win95 was, though, that your local egghead did stop selling
4MB PCs. RAM was expensive those days, and one of the things that KEPT users
from installing 'real' OS (like OS/2 or probably even Linux) and using them
was that most PCs didn't have more than 4 MB of RAM.
So the cycle was this: Get OS/2, install, see it crawling because 4M isn't
enough, start ranting, delete it, get Win95, see it crawling, upgrade your
machine because you suddenly don't seem to have a choice any more, So:
OS/2 is dog-slow -> OS/2 sucks
Win95 crawls -> your hardware needs to be upgraded
