Definitely has t to be an AGP 8X video card and it does not have a PCI Express slot!
Faster data transfer rates:
PCI-E > AGP > PCI
some links for an AGP card for your motherboard:http://www.newegg.com/Product/Product.aspx?Item=N82E16814150433http://www.newegg.com/Product/Product.aspx?Item=N82E16814102814
I prefer XFX because they have lifetime limited warranty compared to others that have 2 or 3 years. I have a PIC-E XFX card which is treating me well and hope to stay like that. Please don't forget to check the Power Supply requirements for whichever card you are planning to buy.
