I am looking for a better CPU because i recently found out about "bottlenecking" and my AMD Athlon X4 750K Trinity maybe bottlenecking my Saphire dual-x r9 270x. i was looking at the amd fx 6300. any recommendations?
Stick with the athlon x4 750k and oc it. Getting the fx6300 will require you to get a new mobo. If we're talking bout bottleneck as in 5-10 less fps in games, then its not worth the cpu upgrade. The r9 270x is also not a very high end gpu to begin with. There will always be a 'bottleneck' in a system, as there is always a component of the system that will hold back performance and can be improved on.
