My system sure seems slow after upgrading from Phenom II 1100T to FX 8350. Phenom benchmarks higher than FX both running at 4.1Ghz well I took FX up 4.6 that is slower that 4.4 and the o/c is still lower on benchmarks as the Phenom 1100t. would it be my MB GA-970A-UD3 plus I'm running 16 Gb of DDR3 1600 that will not let run past 1333mhz on boot if set to 1600 goes back to bios showing overclock set to high. Any suggestions
My NB clock set at 2400 and HTL 2200 stock.... I set both at 2400
is my system bottlenecking?

Yes, your system is bottlenecked by your chipset.

I got the FX 8350 and it was trash compared to my previous Phenom x4 955. I couldn't find it in my logic to accept such a thing so I started digging around the net and eventually swapped around 4 different motherboards before settling with the Asus Sabertooth 990FX Rev. 2.0.

How big the difference? Playing LoL on the old CPU I'd get a solid 50-60 fps; playing with the 8350 on the first motherboard bought (970 chipset) and I got fluctuating 20-30 fps and in intense fights it'd drop down to 3-5 fps; playing with the Asus Sabertooth I get a solid 60-70 fps and drops to 50 when intense fights occur.

Yes, I'm aware that the Sabertooth isn't the cheapest board out there but this is the...

Yes, I'm aware that the Sabertooth isn't the cheapest board out there but this is the solution I found 1.5-2 years ago when the 8350 was also relatively fresh on the market. Nowadays I'm sure you can get another motherboard that works well with it; snoop around a bit ;).

Good luck!

There is absolutely nothing wrong with pairing an FX -8350 with a 970 chipset motherboard with an 8+2 power phase. Its compatible (check Gigabyte's website) and more than capable enough. The only difference between it and a 990FX are fewer PCI-E lanes for Crossfire and lack of SLI support. That's it. You definitely won't be "bottlenecked" by it.

O.P., make sure your board has the current BIOS to support the Vishera processors (BIOS F7). The most current for your board is BIOS F8f.

You might want to update your chipset drivers as well if there's a more current version than you have installed. As far as your memory goes, the FX processors memory controller is set to default 1333 Mhz. Anything beyond that is an OC and that takes a little more work to get right sometimes.
