What's the stock clock on a 4350? Is it the 4.2Ghz he mentioned? 760 MOBO is crap. That GPU is crap. I had a Sabertooth 990FX when I had my FX-6100. Was great for overclocking. Only reason I upgraded was because the board only supported PCI-e 2.0 and didn't support over 1866Mhz RAM.
Nicholas Fletcher 350 isn't actually that bad but the GT 730 is why its bad, my old obsolete phenom ii x4 945 machine with an rx 460 12gb ram and a 600w psu would probably fetch about 350 if i were to sell, it, certainly would beat any 500-600$ prebuilt that has similar parts (fx 4350 is actually about the same) still, i don't really know why someone would want that kind of obsolete tech
