I am building a budget gaming rig using an AMD Phenom II x4 955 quad-core processor. I need an AM3 socket motherboard for around $100-130. It needs to have Crossfire capability (PCI Express 2.0 @ x16 and x8) for a pair of HD 4850s I am throwing in. It also needs to support DDR3 1600 (at least). Can anyone help by recommending a motherboard that fits these specs? Thanks.
