My opinion is that ddr2 is still good. There is little diffrence between ddr3 and ddr2. The speed is unnoticeable. The only scepticle thing is the price. Ddr2 sticks are WAY more expensive than ddr3 sticks BUT, if you look at ddr2 boards vs ddr3 boards, most of the ddr2 boards are cheaper. Personally, upgrading to ddr2 is NOT worth is performance wise unless you are using lga 775 (I'm an AMD guy) What do you think?
