AMD has been equated to "gaming" but the truth is, any system would do... murag wala man siguro processor nga optimized for gaming... of course for the past few years, Intel has been seriously kicking AMD's butt as their processors seem to be better overall... AMD's response though seem to be with the pricing, so you can get more "value" rather than "raw" power...
no fanboy stuff ha, AMD user baya ko...

but if i am to build a PC now for gaming, i'd choose Intel 2500k and then at least a GTX 560Ti video card...
