Not with that board at least. The motherboard doesn't support the x5482's bus speed, nor would it be able to handle the heat that thing would give off.

Why would you want to do such a risky mod anyways? Q9650 would be less of a headache, plus there's no danger to damaging your motherboard, because if you screw up, the cheaper mod can end up being more expensive than if you'd just get the fastest cpu officially supported by the board.
Or just save up for something new, as that platform is pretty old anyway.
