I am building a new system within the next couple of months, and I am not sure wether I should get DDR2 or DDR3? DDR3 is newer and faster, and more EXPENSIVE, but DDR2 is cheaper and still faster than what I got now. Keep in mind that whatever you suggest, it needs to be upgradeable in the future. I will not be buying a new mobo for at least 3-4 years. So I am building a nice system that will be upgradeable. This decision of memory will determine what mobo I choose. Thanks for your suggestions. Oh and by the way, this will be almost completely for gaming.
