I've been trying to read up on the limitation and i see windows uses some of that 4th gig of ram to do stuff so we cant use it. fine
so if i only have 3 gigs of ram does windows use that same amount of space, thus making my 3 gigs less than 3 gigs, in effect?
if so then 4 gigs is a no brainer.
however, upon further thought, since the RAM is priced with no benefit to buying more/getting cheaper, i think i'll start with 2 1 gig sticks and if i need more just buy more later. RAM only gets cheaper right?
