Upgrading from AMD fx-8350 to fx-9590 cpu on ASUS sabertooth R2.0 motherboard. Need to know reliability given the cpu has 220w requirement yet motherboard manual says AMD 140w supported. Since cpu came out after motherboard was spec'd, I am thinking the motherboard will work well since it is supposedly mil- spec with heat treatments. I use 750 ps and cpu water cooler. My concerns are overall PC reliability related. All feedback with people knowledgeable with sabertooth or fx-9590 will be appreciated!
