You have the EE version of the 4800X2. It "should" work, but even if it does it won't be fully supported in that it won't run at the voltage it's suppose to so you will probably have to run it at a slightly higher voltage. I'd give the board a 60% chance of posting, going by the CPUs supported. It would be more likely if this board also supported Phenom and Phenom II CPUs, but I think Biostart artificially limited the board strictly to low end CPUs to encourage you to buy a more expensive board.
if $50 is your budget this board is miles better
