My current set-up is an hd 6970 and an a8-7600k (I know, pretty cheap and bad), I'm on max power settings on BIOS, and I get like 70 FPS average on the CSGO benchmark test 1080p low, and about 80 FPS with an HD 7770 same cpu(same settings). In addition I had little to no background programs on both tests and I'm really starting to question things. First a guy told me I had a CPU bottleneck, but when I plugged my specs into thebottlenecker.com it said I had a 10% GPU bottleneck???

Incase you wanted some of my specs here it is.
Everything is at stock clock.

a8-7600k
xfx HD 6970
g.skill ares 2133 mhz 8gb ddr3
1tb barracuda 7.2k rpm


I'm honestly not sure what to do, in other games performance is relatively the same, in tf2 on low 1080p I get around 60 fps but it can dip down to 40. Should I just get an upgrade, if so, for what part?

Hi there,

The frame dips you experience in TF2 are due to CPU bottlenecking. However the CPU bottlenecking is minimal and only occurs in CPU intensive scenes. You get smooth gameplay during other times.

CS:GO is a CPU intensive game and your frames there are limited by your CPU. In my opinion, if you do want to upgrade, a complete system upgrade is necessary. That being said 40fps is still playable and the upgrade would depend on your budget. To sum up; you are experiencing CPU bottlenecking though it is quite minimal since your GPU isn't great as well...


Usually upgrading the GPU is recommended. I wouldn't recommend an upgrade of the CPU alone as the FM2+ socket is pretty much outdated. Here's an upgrade I would suggest...

Terrible website, there's a much better way to see if your CPU is holding back your GPU. All you need to do is play the game on high settings for a bit and note the FPS then lower it down to Low settings. If the FPS increase then your GPU is reaching it's upper limits, if the FPS doesn't change then your CPU is the issue and should be upgraded if higher FPS is needed.

Yes, I've been thinking about a CM 212 and i5 2500k combo OC to around 4.5

I don't know what kind of PSU you have so I didn't add one in. Also you never gave a budget so I picked up decent low-mid priced components.
