Ok when will the extra ram make a difference? I just bought a 21" CRT. I am thinking for the higher resolution for the bigger screen I will need the ram compariing it to 128mb performance on a 19' CRT? What kind of res am I looking at with a 21" CRT using a AGP GF 5500 w/256mb AGP GF 5200 w/128mb will the extra ram make a big difference for lets say these games: I.e. For SW Battlefront? KOTOR II? Doom 3?
