Hey I want to upgrade my compaq computer and in order to do so i need to buy a new motherboard graphics card and processor. I know two of those three things. I am getting a nvidia geforce 8600 gt and a AMD phenom quad core. But im not sure about the mother board. I am on a budget but i dont want to buy crap. I just want everything to work like it should. If you could please give me suggestions that would be great. Thanks so much.
