I'm still using the computer in my sig, but I've decided to upgrade to 2GB of RAM. I don't really understand the principle behind Dual Channel (I read the FAQ, but perhaps I'm not dedicating enough time to grasp the concepts).

Anyway, I currently have 2x512MB in my machine. If I purchased the same sticks of memory and upped it to 4x512MB, would I notice any significant difference than if I instead bought 2x1GB sticks?
