FX 6350  vs 6300 

That said you don't really need to have an overclocking mobo to push the Core i5 up over 4.5GHz and gaming performance will quickly outstrip the AMD chip.

if you haven't realized amd always does this 8320-8350 8350-9590 6300-6350 4300-4350 simple solution stop bashing amd fucktard, buy the lower model and overlock it to match the performance. oh don't you remember the time haswell i5 and i3 were barely an upgrade from ivy bridge, oh right intel fanboy that doesn't matter shit
asus m5a97 am3+
well, amd sells the same cpu 40 euro more expensive and the real difference is the 400 mhz more, gg amd
What's a good low-price motherboard for the 6300? A good one as in overclocking, etc. Thanks!
I bought the 6350 a year ago because it came in a bundle with my MOBO and ram for $70 off.
Stock overclock is a warranted overclock speed and stability.
yes but, the x versions or higher clocked versions are also better binned meaning they have better silicon in them.
OK AMD really needs to stop crap like this! All the 6350 is, is a warmer running overclocked 6300 at the same price as the 8320 is, When you can just overclock the 6300 and pay much less. I am grateful for my R9 270 because I was able to get a R9 series card for under $200, But still both the 270X and 270 are the same. And the 270X costs more for just a higher clock you can do yourself, When they should have just priced the R9 270X under $200 to start with. Just like when they came out with the FX-6350 they should have priced it the same as the 6300 and dropped the 6300.
I'd say the 6300 clearly wins, with a lower price point and better overclocking. as well as the lower tdp. it probably would have come out ahead on this site if price was factored in.
another one that's extremely close "too close to call" imo. can't go wrong with either one. Though I prefer the 6300 as it has a lower TDP
