So right now i have a 512stick of RAM, 400mhz in my motherboard. The motherboard supports 4GB. I am thinking about adding another stick, to have at least 1 GB. I've been telling myself I will for some time, but I found a cool looking game called VegaStrike (1st person space shooter).
So would I get better performance by getting another 512stick and running it dual channel or whatever that is called? Or, better to buy a 1GB stick and simply adding that in.
