6GB is better than 4GB, but in all seriousness, the Haswell Pentium based setup with 8GB DDR3 is the best setup you can buy for the money and linked with a much faster GPU. The Pentium is faster than either of the Phenom II processors for gaming, period. The 3258 can also overclock and when overclocked can rival i5/i7 performance very easily giving you even more of an edge over the old AMD CPU. Not to mention future upgradability.
