I don't think another gig is needed, however, if you plan on switching to windows 64, then I suggest getting the extra gig. A video card would be a better investment for now. I have a 9700 pro and I am already thinking about getting a better one. I get a score of 2000 on 3dmark05 which is not where I would like to be. I have 2 gigs or ram on my computer and with windows XP it doesn't use much of it. but when I was running win 64, I was using 400+ MB and I wasn't running any programs other than windows. The only reason I switched back to win XP pro is because I wanted to put my hard drives in RAID and they don't make any 64 bit raid drivers for my setup yet. I hope they make them!
