i was wondering if all these new other boards are compatible with DDR2 memory anymore? because i'm using a leonite2 mobo on a prebuilt computer and i'm thinking of upgrading a lot of things. I have the HP Pavilion a6120n computer. Am i better off buying a new computer? All I did to upgrade this computer was add 2 sticks of ddr2 ram and a nVidia Geforce 9800 GT.
