I need someone to explain what card to use with the "GIGABYTE GA-890GPA-UD3H AM3 AMD 890GX SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard Item #: N82E16813128435" Mostly video editing but also some light gaming and around $100 give or take. I had planned on using "HIS H467QS1GH Radeon HD 4670 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card" but not sure now. Any supporters out there ?
