I didn't say or assume that he has an nForce2 mobo, it's just the first that comes to mind with dual channel memory.......and dual channel is the only thing that I can think of that would give any performance increase by running 2 sticks. I believe there are also some Intel boards that support dual channel. But if I recall, you dont' really see a whole lot of increase in overall performance unless you're usuing the nForce's integrated graphics.
