Do I have a serious bottleneck or faulty components?

My CPU is the FX-4130 while my GPU is the SAPPHIRE HD 7870 Dual-X GHz Edition. I think it may be a bottleneck. The problem is before my games would run at a good fps but would drop every 10 seconds. I found out it was a heat issue with TMPIN1 (CPU or NB I'm not exactlysure) and throttled itself when it reached 65 degrees C. I fixed this by installing a new case fan, and that fixed the problem.

Sadly, short after, my cheap 500W PSU died on me, but no components went with it. I replaced it with a Corsair CX600M PSU which is running very fine, but it was after his I realised my games weren't performing very well as they used to and that my GPU Usage would fluctuate and never hit 99. I've also realised that it will only go up when in non detailed environments, but when in populated areas the usage will go down by 40% (Maybe due to the CPU). I can only narrow it down to two things.

1. I have a terrible bottleneck that just happened to appear.
2. The cheap PSU that blew up damaged my graphics card/CPU in some way

Any help will be greatly appreciated.

What exactly is happening when you game? I reccommend Downloading and installing MSI afterburner just to keep an eye on the GPU temps,usage,memory and voltage. That way you know how mcuh of you GPU is being utilized

Also Keep the Task Manager open as well as the resource monitor. That will give you your CPU usage. I guess you can game in windowed mode to see what is happening with your CPU

I already have MSIAfterburner and here is me playing AC4 with my CPU usage to the left hand side http://imageshack.com/a/img841/8356/ykjw.jpg. Now, I have now encountered a new issue with my GPU. The memory clock stays at 1200MHz constantly while the memory clock doesn't downgrade past 450 and my PCI-E stays at 2.0 and doesn't go down to 1.1 when idling http://gpuz.techpowerup.com/14/04/20/g94.png and http://gpuz.techpowerup.com/14/04/20/b8d.png.

Right now I'm running a full scan can on my computer to see if any viruses are causing this.

I have that issue to with my GPu running at stock(1046MHz) while in 2D/desktop mode and or idling. It only seems to happen shortly after a driver install. So I am looking into that myself Fortunately the Voltage is only 1.050v and the temps are 36°C. But returning to your "Bottleneck" conundrum, It looks like it might be a driver issue or other software issue as Your CPU is not even using a full load( 99% to 100%) so your FX 4130 is sufficient for the Radeon HD 7870. Also not Every game is going to put a 99% load on your GPU. AC4 should but remember AMD is still working on their drivers for that game. There might be one out now that works better. I will look into it more...

Also your graphics card is not running that high of a frequency compared to mine or is that an older PIC..

And just to make sure you should run Unigine Heaven 4.0 or Valley 1.0 and put the graphics settings all the way up

I fixed my clock issue thankfully. With the GPU issue, non of my games run at 90-99% usage anymore.

My GPU Usage is constantly at 99% when doing it and here is the result http://imageshack.com/a/img841/2158/9qy0.png

Cool...Good to hear. So you the CPU does not run at 90-99%, yeah?
