If you are using phenom i with that gtx 580, god you are under some serious bottlenecking. If you are using it with phenom ii @ stock, god you are under some serious bottlenecking still.
How much money you got? I think your mobo does have future support for am3+ cpus(just got to love asus
) . So, probably if BD does comes out good, your rig will truly get awesome IMHO.
