wouldnt a sil1364add2-n (http://www.pricedbelowmarket.com/...ets/img/255163_4_600w.jpg) digital card work in my motherboard? my video card currently is an ati hd 4870 series (http://www.newegg.com/...spx?Item=N82E16814103193)

Asking because i placed the sil1364add2-n in my computer but it didnt work, but the card does work here at work in the older computers.
