After having this CPU for a while, and seeing it get through most stuff I throw at it, it has finally gotten to an end point. While it-games I see my CPU usage go up to 100, yet the GPU stays around 46, and occasionally jumps up to 100, and of course that's when I see playable fps. Oddly shadow of mordor seems happy sitting at 60 fps all the time.
copied your pc specs. You could (if you haven´t allready) take a look at what you system is doing with MSI afterburner.
In case your usaged look similar to the following, I have bad news for you: Bad codeing, nothing you can do anything about.
Its not really that strange.
The main problem with these Athlon cpu´s is that they are basicly based on the same principle design as Bulldozer and Vishera, which means CMT design.
Those cpu´s are basicly not really true quadcore chips.
They have 2 modules with each 2 integer cores sharing cache, decoder and fpu.
And thats the reason why the dont perform like a true quadcore.
So its not really that strange that you get bottlenecked in certain games.
GPU´s have become more powerfull over time, then they were back in 2011.
Another additional problem is that those Athlon chips lack on L3 cache aswell.
Yeah, but how is an Athlon X4 750K bottlenecking an RX 460, that's not a powerful card by any means. And the X4 750K is about 15% behind an X4 845, which as far as AMD goes has the highest IPC, want higher than that, that means go for a Zen CPU or an Intel CPU (Skylake or Kaby Lake, or even Sandy Bridge i5 2500K has a 40% lead over an X4 845)
I think that a RX460 is about 7870 / 270X performance.
Since i own a 7870GHz card + a FX8350.
I can tell you that my FX8350 even bottlenecks my cards in certain games.
Plain vanilla Skyrim, Cities Skylines, just to name a few.
Those AMD chips are simply starting to show their age.
its sad but true.
FeelsBadMan, AMD is too dated in the CPU department, good thing I recommended a friend an i5 6500 since he was gonna go for the FX 8320E (I think it was called, it is $90 at MicroCenter, great for a cheap ass NAS, but we have those cheap Xeons for that too)
The fact that an underpowered GPU like the RX 460 is being bottlenecked by the CPU is woeful.
Well of course it all depends from game to game and how you play certain games,
on which particular settings.
But yeah i think that its pretty fair to say, that at this point in time,
with Ryzen at the horizon, and Skylake / Kabylake, it might be worth concidering to upgrade if you are currently on an older am3+ or fm2+ platform in the near future.
750k can really bottleneck any gpu... Keep in mind this is 4-5 years old budget even at the time processor, paired with low budget gpu, that was top of the line 3 generations ago... I mean really, 7870 was really really powerful card back in the day.
Especially in Cities Skylines, as @MisteryAngel said...
The system is still balanced well, there are trillion games, that will work just fine. But there are many games, that will suffer, because of the cpu. I mean Doom runs pretty much the same on pentium and i5... But then there is GTA5, or Cities or games, that eat CPU like nobody's business...

Yep it all depends on the games you play an how you play them basicly.
But certain games that demend on the cpu allot, or certain newer AAA games,
that really benefit from having 4 or more cores.
cpu´s like a Athlon´s and such just start to suffer.
Funny story, I built a Mini-ITX computer, unfortunately the motherboard would not support the Athlon X4 845, so instead I had to resort to an A4 5300B I got on Ebay for $18. Yeah, for CPU bounded games, it performed as bad if not worse than my tablet (although it stomps in the GPU department).
Surprisingly, the computer only drew around 120W from the wall compared to my big desktop's 500W machine.

This is because Shadow of Mordor is a gpu bound game.
Thats basicly why you see a pretty okay performance.
But there are also games that still use the cpu a bit more.
And those are the games you will see a reduction in gpu load and fps.
Like i mentioned it really depends from game to game, and also the settings.
Sometimes you can tweak arround with settngs to get a bit better performance.
But for certain games your cpu will be a limmited factor.
Yeah, I understand why it's not doing very well in some games! It really only has showed now that my GPU is being held back a good bit.
I already am! I have ordered a 3470 ivy bridge CPU, and I know that's bad for upgradeability, it is a considerable upgrade from what I have now.
But you also gonne need a a socket 1155 mobo for it.
ye athlon x4 750k is bottlenecking hard rx460, also i've found out that my rx460 is lowering core clock cuz of power limit, (since it has no 6pin conn) so i've simply increased power limit in afterburner (which works great without any issues unlike radeon wattmanbullshit that crashes randomly) and perfect example of bottleneck is Assassin's creed III, getting 30fps max(25 average) and that game is so old, oc the cpu and youll get few more frames but nothing really amazing around 10% is max :/
Unless ryzen makes thing happen, I don't think that any1 would use amd cpus unless hometheater build or smthing like that (don't know about fx 8core but I guess those aren't so great too) :/
VSR, Virtual Super Resolution, turn it on and jack the games res up, should take some pressure off the CPU and maybe help out the frame rate a bit. Wont work all the time but worth a hold over shot.
