I have the same question as SrgtGoat. I am also going the way of Q9650 and want to know the best board available. I would think it is the P53E but just wanted to make sure. Any recommendations on RAM would be appreciated as well. I am thinking about the Corsair Dominator XMS2 8500. Planning on running this with PC P&C 750 W supply. Also planning on getting a 4870 X2 and go crossfire maybe in the future
