Is there any way to hook my Xbox up to the HDMI port on my motherboard and capture game play through my motherboard or do i have to get a capture card?
Yes, you will need to get a capture card of some sort, as well as some software to do so. Normally by purchasing the hardware you'll get the software with it. This is a very good capture card, although a bit pricey. http://www.newegg.com/Product/Product.aspx?Item=N82E16832252057
