I have recently become a little dissatisfied with the speed of my pc and its ability to multi task. I currently am running 512mb of ram in 2 256 sticks. I really dont need a big boost to performance, its just running my online addiction, FF XI, winamp, and a downloading program all at the same time tends to make my game run a tad on the slow side for me so i am looking for a small boost. If i were to upgrade one of those 256 sticks to a 512, would there be much of a difference, or would i be better off going for 2 512 sticks, my mobo only has 2 ram slots.
