I happen to have an unlocked x4 555 as well as an i5 530, and there is no way an i3 530 beats it in half of AT's benchmarks. Again, an unlocked x4 555 performs similarly to a Phenom II x4 965 and 955 (both ahead of i5 530 in many of AT's benchmarks) seeing that the only difference with the three are clock speeds, and the chart by Passmark that actually includes the unlocked x4 555 (B55 in
this chart). What's to stop the OP from overclocking the 555 as well?
