liberato87, you can buy a mobo 990FX for about 120 euros like mine Gigabyte UD3 . It doesnt have to be a highend mobo.

Asus CIV might support BD, check in asus site. At least some old MSI and Asus mb support BD already. Better wait and see.

If I was you, I'd run the old mobo until next BD2 if the old mobo supports BD.
