Well fix ur post to MSI K8n Neo2, that one is 939, while Neo is 754.
I just had to choose between those 2 setups same as u... and i went with the 939 route... hoping to OC well...
But either one should be great.... with 939 u will have to OC it to 2.5ghz.... few plp are going all way to 2.6... so what u getting is relle just 100 or 200 MHZ extra...
either setup would be good... if DFI had a NF3 939 mobo out... the choice would be clear n simple then..
