Where is the bottleneck in my computer build?

Good evening,

About 3 years ago I built a new gaming PC which I figured would last me a very long time, and has for how fast technology is released. Since building it I could play most games at High/Max settings, lately though my computer has been having FPS issues and not being able to keep up on med/low settings for some games.

So this brings my question to light, is there a bottleneck with my PC build and what is it?

Processor: AMD FX-8150 Zambezi 3.6GHz Socket AM3+ 125W Eight-Core Desktop Processor
GPU: GIGABYTE Radeon HD 7970 3GB 384-bit GDDR5 PCI Express 3.0 x16
Memory: CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) (Also why is this memory so expensive now? I purchased for $94 in 2012, now it is $179...) Also one stick died so I am using 3 sticks of ram.
Power Supply: OZC Fatal1ty 550w Modular PSU
Mobo: ASUS Crosshair V Formula AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Gaming Motherboard with 3-Way SLI/CrossFireX Support and UEFI BIOS
Hard Drive : Samsung Evo 840 720gb SSD and couple 128gb SSD's by OZC

Games I play:
DayZ - Barely Medium graphic settings
Arma 3 - Low/Med settings (Altis Life, Battle Royale, Epoch Mod)
Battlefield 4 - Med/High Settings
Skyrim - High Settings
Fallout 3 // New Vegas - Max settings unless running massive addons, then it bogs down.
Archeage - Medium Settings to play smoothly
Sims 3 - Max settings but it bogs down in a big way when viewing city.
Simcity 2013 - Max settings but bogs down sometimes when city size is massive.
Borderlands 2 - Barely playable at certain points of the game at any setting. (If not much is going on it runs smooth at max settings, but shit hits the fan very often in that game)


Thank you for your time in helping me with my issue, I really do appreciate it.

I would suggest upgrading your CPU to an AMD fx 8350 as the 9xxx series really are just factory overclocked versions of the 8320/8350, and I would slightly overclock the CPU. I play dayz as well, and I am making a build so it can run dayz and other games well, and I know that dayz and arma are cpu reliant games. Either way, you will probably have to upgrade the cpu to keep up with the latest games. Also if you do decide to overclock the CPU just make sure you are well in with your power supply to avoid unnecessary issues. Apart from that, you should be fine, I can't find any other major bottlenecks, I believe it is just your cpu.

Btw dayz is a very unoptimised game atm, so even if the cpu is good, it doesn't mean that the game will...

No I have not, I recently got my twitch stream setup perfectly. Re-install would be a last resort if that is the only thing holding my rig back.

I run a two-pc stream setup, so the encoding is done on a separate computer. Should not effect gameplay.

Hello,

Firstly, check the temperatures for the CPU and the GPU. If too high (65C for CPU, 80C for GPU), clean all the dust from all the fans (the case fans included). Also, install HWMonitor or HWinfo, let the program running and see the minimum voltage values, especially from the +12V (your PSU is a good quality one, but in time the power output gets derated, so maybe it cannot cope anymore with the load of an FX8150 and an 7970).

Btw dayz is a very unoptimised game atm, so even if the cpu is good, it doesn't mean that the game will still run smoothly, I know this from experience, as I had a laptop and it ran a very bad i3 processor, and I managed to get 20 fps in cherno and electro and 50-60fps everywhere else, strange right?

Upgrade cpu possibly to either a 8350 (8370 is almost the same, just a difference of a few 0.1 or 0.2 ghz) or change your mobo and upgrade to an intel processor, such as an i5 4690k which is much faster than the 8350 in terms of single core performance, and will probably run the games you play better, but it is up to your budget, both processors are great though, and you can overclock both provided you can safely do so with your power supply.
