I'll explain myself a little further. I don't hate the FX cpus and they are not terrible. There WILL be times when they outperform the i5. There are a handful of games that prefer more than 4 cores. It's just that MOST of the time, like 90% of the time, even the "slowest" Haswell i5, the 4430, will outperform ANY FX cpu no matter how much it's overclocked. Since overclocking the FXs are basically a must, it takes away from their value when compared against a locked i5 because you have to pay extra for a better motherboard and you have to add in an aftermarket cooler.
The R7 265 is a litle better than the GTX750ti for about the same price but it uses a lot more power. They are a push.
The GTX760 is better than the R7 270x but it is also more expensive. I prefer the 760 here.
The R9 280x is a little better than the GTX760 but it is also more expensive. They are a push.
The GTX770 is a little better than the R9 280x but it is also more expensive. I prefer the 770 here.
The R9 290 is a good bit better than the GTX770 and it's only a little more. I prefer the 290 here.
The R9 290 is about as good overall as the GTX780 and it's cheaper. I prefer the 290 here too.
The R9 290x is almost as good as the GTX780ti but it's WAY cheaper. The 290x is an easy choice here.
