which one is better, performance wise.. this is not for Gaming.


laborare est orare
The performance difference is very marginal. So get the Athlon II X4 645 and saves the extra money. You can always overclock it to Phenom II X4 840 level to get the same performance. 840 is not a true phenom II, it is a re-branded Athlon II without L3 cache.

Both are based on Propous chip, don't be fooled by the Phenom branding.

Go for the cheaper one bro

Basically Phenom II X4 840 stands for what would have been Athlon II X4 650. If you are comfortable with OCing, get the 645 and save some buck. ;)
