Alright the title is a little off, my question is actually about the amount of RAM needed, but eh So in my upcoming rig I have the option of having 2GB or 4GB of RAM. 4GB adds £100 on to the initial price. Should I just have 2 gigs and upgrade in the future, or would it be simpler to put all the RAM in in one go? What games need more than 2GB of RAM anyway??
