Processor

equivalent to a core 2 duo, if not a bit faster. also considering that chip has integrated ddr3 controller helps as well.

Pentium G620 is a very good chip, and roughly equivalent to Core 2 Duo E7600 (3.06 GHz, 3 MB L2) (actually, better than it).
It also has additional advantages of:
* Sandy Bridge (2nd Generation)
* Strong Integrated Graphics (Intel HD2000 Graphics)
* Energy Efficient, lower TDP (only 65 W)
* DDR3 Memory Support
* LGA 1155 Socket, which means that you can upgrade it to i series in future.

So, if you have low budget, it is a very nice option.
