no right now the sweet spot for windows is 2gb ram. i have heard that 4gb actually slows it down but i have not had experience with that. right now i have 1gb valueselect ram and its fast enough for me.
lol wow i feel dumb that's the smallest sig i've ever seen, i had to put on my glasses to read that. yeah i'm aware that windows would run horribly on 4GB of ram.
