Please help me choose a motherboard

DDr2 or DDr3 ram?

I just bought an Asus M4A89GTD PRO/USB3, maybe take a look at that (I'm still waiting for it to arrive). It has usb3 and a bunch of the newer features. Good Luck

Hi newcomer and welcome to the Tom's hardware forum.

1- What budget do you have for the mobo?
2- Do you want install one GPU or two GPU (Crossfire)?
3- What RAM speed do you have?

thanks for the advice. Moderate budget around 125 for the mobo, I am only running one video card and I am gonna install ddr2 but will upgrade when ddr3 becomes cheaper. thanks again

Wel DDR2 is actully more expensive then DDR3 is. If you want to go DDR3 later you will have to get new motherboard.

This is a great board and will unlock your 4th core also uses DDR2

If you already have DDR2 ram avaliable use it but if you have to buy new ram go DDR3

Well, with your GPU and CPU isn't a good option that you install this in a AM2+ mobo with DDR2.

You can get a new mobo and DDR3:

RAM: G.Skill 4GB 1333 CL7 $104.99 with free shipping.
MOBO: M4A77TD $74.99 after rebate and free shipping.

Total: $ 179.98 after rebates and both with free shipping.

Is a good upgrade option for you.
