I play alot of on-line games and I came across this dilemma while deciding which graphics card to purchase. Would it be a good idea to purchase an additional 512 MB on top of a graphics card that comes with 256 MB on it already or should I just get a graphics card with only 128 of ram and still get 512 MB? Or just don't even bother with the additonal computer memorary and stick with a graphics card with 256/128 MB.
