sure, everything runs pretty well, but if you mainly game, an i5 of the new haswell generation would give you a better experience because it has a much better single-threaded performance
most muliplayer-games are cpu-bounde, they benefit from that performance
i choose the fx 8320 because I mainly use this pc for my work as a programmer, where i can benefit from the 8 cores and yeah, I love amd, I've always had amd cpus and gpus and I will stick with them
but in terms of raw processor perfomance, nobody beats the intel haswell generation at the moment, that's just facts
maybe not always on paper, but in terms of gaming for sure
