My friend is currently running an AM2 Motherboard on a compaq, which means he can't change cpus or overclock. I have suggested to him that he buy a new motherboard, and use his old CPU until he can afford a new one. My question is: If he buys an AM3/AM2+/AM2 motherboard, will he be able to support ddr3 ram? and will he be able to take full advantage of a Phenom II? Any advice is greatly appreciated. Thanks.
