FX6300 is a lot better and those who make comparison by power consumption and stock cooler are idiots .
so choosing FX6300 doesn't mean that mobo's for it are pricey actually they are cheaper if you compare to i3
and you will have a lot more money to spend on graphic card , RAM , HDD ,SDD etc ...
The original poster explicitly said he wanted a CPU with low power consumption.
More power consumption means a more expensive electricity bill, and more heat is generated. Even if you can keep the CPU cooled sometimes this can increase your ambient room temperature.
Plus, an Intel motherboard on a Z97 chipset will mean that he can make the upgrade to a bigger, badder Intel CPU later on, such as the i5-4690K or even the i7-4790K. While the i5 might have to tangle with the FX-9000s the i7-4790k is indisputably above any processor AMD makes.
