haha this is odd.
i have the same computer.
yours is a dimension 3000 right.
and i tryed upgrading it, so i bought a new processor, mobo, and vid card and then realized nothing works.
so now i have these parts that i cant send back =(
and i cant rebuild a pc because the parts arent too great.
=(. never try upgrading a dimension dell desktop.
but yeah 2GB will run relatively faster than 1GB, although some have the notion that its no difference.
i think 4GB from 2GB is unecessary but that also makes a difference.
you cant take the kid from the fight, take the fight from kid.
