if u dont mind spending money or a new board get a new MB
a controller card will work but you will need to install drivers and stuff if you first use and or formatted and the sata intergrated into the MB is much better cuz it has RAID function most of the time. just make sure the board has that function or if you dont use it then it dont matter. check to make sure your board dont support sata or you'll be wasting money.
i would go with an board upgrade rather than a controller card.
i have not seen on board that doenst not support ide but sata only.
just take a long at the pictures or the spec before you make the purchase.
