I agree. 4GB is good for now for both 32bit and 64bit OS. And yea 32bit XP or Vista can't use more than 4GB, I think it can use 3.5GB according to MS's website.
I have 6GB right now without virtual memory and none of my games have used more than 1.7GB ram.
Games like FSX, HL2+it's mobs like TF2 etc, Arma, etc.
When I had 2GB ram, I have to turn on virtual memory which slows things down a lot.
So if you are running one game at a time, 4GB is enough.
Added: 8GB is not an overkill as you can turn off your virtual memory so windows no longer use the virtual ram on your hard disk, swapping between ram and virtual ram. Your machine will fly.
