Getting ready to upgrade my ram. Currently I'm running 256 megs of Kingston 2700 (333). Now here is the question, I'm going to be buying a new mobo which will probably consist of a P 2.4 and a MSI board to replace my AMD XP 2000+ and MSI board. Will I notice a huge difference between 333 RAM and 400 RAM. Meaning, should I ditch my current Kingston 2700 (333) RAM in favor of a stick 512 meg of 400 RAM. Or would it be wiser and cheaper to just buy another 256 meg Kingston 2700 (333) RAM. Obtaining 512 megs of RAM is the goal here while also referencing the acquisition a new mobo and chip.
