So, currently running a mobo with ddr2 667. Looking to upgrade to a 1333 mobo because i have a proc that supports up to that, plus the mobo is kinda low end, it was just meant as a replacement. I've been tending to lean towards ddr2 because it's much cheaper. Is the performance boost from ddr3 worth the money to invest in a board that supports it? if not i was going to upgrade to something supporting ddr2 1066 or ddr2 1200.
