proc with FSB1333 already out there for a while, got ppl use e6750es.... Intel just inclease the fsb form 1066 to 1333 and rename to eXX5X series... the rest still same, even Q6600 can oc to archive that FSB

ya, intel want to sell out all old stock proc and sell new series.. it still use same LGA775 socket, form top bottom to top end use LGA775 unless intel officially introduce new socket, but so far current socket able to support current intel proc architecture
