honestly, unless you play a lot of games and have a million things going on at once, i wouldn't upgrade just for the sake of it. it's not worth it. i still use my gf's computer which i built for her, it's a 1600+ AGOIA, heck, i just ripped 15 movies on that computer. unless you're hardcore and you're going to play UT2004 and FarCry or some of the other intense games, i woulnd' t upgrade. for everyday use, the 1800+ should be more than sufficient. give it some more ram.
