The 640 is a full quad while the 555 is a dual core but with the potential of unlocking up to two other cores. My daughter's fiancÚ built her a computer using a 555 and was able to unlock both of the cores and they are stable, but not every chip will do this.
hmmm so is it a safer bet just sticking with a cheaper i3 or i5 ( if there even is one? What would you recommend for a more future proof gaming system the 640 or 555 with that being said?
I guess its an argument of whether or not dual core with more L2 cache vs quad core is better for future games? This person I'm building the computer for has no experience and therefore will be playing it on the safe side and not OCing or changing any default settings.
