depend on if your 2gb of ram isn't enough. When the system is tasked, have you checked task manager to see how much physical memory youre acutally using? If you are pegging it against the wall, then yes, more ram will better serve you than the dual channel. If you're not using the 2gb you have, then no point in adding more. 2gb goes a lot further than most people think. If you aren't using all your ram, post all your specs and well see if theres something else holding your system back.
