Yeah you should get the tri core and i would get this motherboard and i would get the distro that supports phenoms like iPC OSx86 10.5.6 and the sb750 is really good for overclocking and i heard that some biostar motherboards could activate the 4th core on phenom tri core's cause one of the cores is turned off in the tri's for some instability reasons so you could just add a little more voltage and have a 2.8ghz quad phenom 2!!!!
