Greetings,
Don't make my mistake as this is exactly what I did, upgraded to the 8350 from the 4350 only to find out some disturbing things.
First most games rely on single core performance and for some reason the 4350 has better single core performance. Next I saw ZERO FPS increase. Worse yet, I probably lost a few FPS. Luckily for me, I was able to find get my 8350 during Black Friday Nov 2014, so I did obtain it well under current price, but again it is NOT WORTH IT.
In fact I've given up on AMD all together as I've been an AMD FANBOY for almost 2 decades, yes well over 20 years. What a fool I was to not even LOOK at Intel over the past few years only to find that AMD has long dropped the ball and is no longer in the game. Intel's i5 will smoke the 8350 and the Intel i7 is in a different UNIVERSE. AMD upgraded to PCIe 3.0 on the APU's but NOT THE FX, so what gives?
Granted no one has yet to post a video on the difference between PCIe 3.0 vs 2.0 and in some cases 2.0 is faster; but needless to say the gap is 1.5 FPS at best between the two so I am not sure what is up there? Why have 3.0 if it does not blow 2.0 away? But I digress and also must say that 3.0 does have bandwidth advantages so if you plan to use SLI/Crossfire while Gaming, streaming and doing what ever all at the same time you def want PCIe 3.0 and an i7 12 core CPU.
Granted some say the 8350 can Game and Stream better then Intel but again only by a few FPS. When Intel is faster then AMD a BLIND PERSON can see the difference but you need a magnifying glass to see how much faster AMD is.
In 2012 I bought the Asus Crosshair V Formula Z, AMD 2133 Gaming DDR 3 16 gb Kit, 1k watt Corsair PSU, Gigabyte GTX 680 4 GB DDR5 video card, not too many faster cards at the time, plus a full tower case and the FX 4350 CPU. Later that year I bought the MOSFET MB Cooling kit and CPU Water cooling block and put together my first water cooling loop with 2 rads plus a host of bells and whistles just to see if water cooling was for me and sure enough it is... My loop stays round 30c most of the time and maybe as high as 34c during heavy load and mild OC. Needless to say this was a test rig because now I know what I am going to invest in and I will save for it and probably throw this system away or scrap it.
I would not wish AMD on my worse enemy at this point, this is how disappointed I am with AMD. Now that I've said the bad here are some good. Well, there's, well, ummmmmmmmmmmmmm Price and compatibility. My A10 APU with Hybrid SLI and AMD 6950 GPU ran games about 20 FPS less than my 8350 and GTX 680 so that's sort of a good thing, it's a bit faster then an APU. But that's like saying a car goes faster downhill than uphill, so there is that...
As far as video card goes if you have not invested in the 8 gb gtx960 don't waste money on the AMD 8350, put that money into a gtx980x or something like that and stay with the 4350. Again if you Stream, Skype and Game all at the same time get the 8350, but if you are only doing 1 of those things, keep the 4350.
I hope this was helpful to you or anyone looking to copy my mistake...
