I dont mean in price, itss just my mates are saying that one of them with 2gb of ddr3 1600mhz RAM is better than my 4gb of ddr2 RAM, but i am sayng more data can be stored on mine so is quicker as it will have to be accessed less, they are saying because theirs is double the speed it has to do half the amount of work. I feel this is wrong, help me argue or argue against me.
