Which CPU is faster?

[Guest]

Hello,
Which is faster, the AMD Phenom II X2 555 Black Edition, or the AMD Phenom II X3 720 Black Edition?

Here you have a comparison:

Anyway, if you choose the right mobo you can try to unlock the other cores.

Thanks!

And by the way, as I would like to try unlocking the remaining cores, which mobos should I consider purchasing?

The South bridge must be the SB710 at least. The newer SB750 and the SB850 work too.
Here you have some good options:
Gigabyte GA-MA785GM-US2H "AMD 785G/SB710" DDR2 ACC HD4200HDMI ALC889A
Asus M4A785D-M PRO "AMD 785G/SB710" DDR2 ACC HD4200HDMI VT1708S
Asus M4A89GTD PRO "AMD 890GX/SB850" DDR3 ACC HD4290HDMI ALC892 SATA6.0
Gigabyte GA-790XTA-UD4 AMD 790X+SB750 ATX AM3 Dual-DDR3
Gigabyte GA-790FXTA-UD5 AMD 790FX+SB750 ATX AM3 Dual-DDR3
Asus M4A89GTD PRO/USB3 "AMD 890GX/SB850" DDR3 ACC HD4290HDMI ALC892 SATA6.0 USB3.0
