Tbh I managed to get a PII 955 to OC to 4GHz stable, with a slight Vcore bump, doesn't go above 50c and that's with a £20 cooler. Not sure about that boards ability to unlock cores, you could get a phenom ii x4 960t, they CAN be unlocked to 6 cores, but not all are stable. If it unlocks, great, if not, overclock it slightly. Judging by your options you've got a budget of around £150? You can get a 960t for around £100 in the right places. Alternatively, http://www.overclock...rodid=CP-253-AM will overclock as well as the 955. That'd leave you money for 1 SSD
