Hi guys i need to know if this is really bottlenecking.

I usually play battlefield 3, on High settings, SSAO, NO AA at 1680x1050 resolution. The frame rate is around 38 - 60+ fps which is reasonable.

On the map Tehran Highway at a 64player server however, my fps drops to 26fps sometimes especially when viewing at a far distance (the US base).

I thought the 6100 can't bottleneck this midrange card. Here are the usage info.

Cpu: 75-80%
gpu: 70% sometimes spikes up to 99% but immediately drops back down.

Is this a bottleneck? BTW singleplayer averaging at 50fps + never drops below 40.

Do I need to buy a new gpu? Or overclock my cpu?

EDIT: When turn down the settings to medium, framerates are good.

Battlefield 3 is notoriously CPU intensive in large multiplayer maps, due to the below average PER CORE performance of the Bulldozer 6100, you will struggle on such a large player map.
Its not really a bottleneck but because you are playing at 1680*1050, your GPU does not need to work that hard, while your CPU is falling behind.

hmmm it would more likely be your gpu certain sections in battlefield drop fps like kharg island on top of that building which is the russian's first flag drops my fps because the view you can see the whole map i would try slightly overclocking your graphics card by 50mhz or so and overclock your cpu aswell. but for the future i would look to be upgrading if your getting battlefield 4. hope this helps :)

I'm playing at 1680x1050 because the framerates are the same no matter what i set it to. Weird :/

My gpu is actually overclocked with 75mhz. Cpu is at stock with turbo switched off. You have a 7770 as well?

Yip, another indication your CPU is lacking. Do you have an aftermarket cooler and decent motherboard to overclock on? Easiest way to test it is by OCing a little.

I cheaped out on mobo when I started this build.
It's an Asrock N68-VS3. stock cooling for the 6100 :(

So this is 100% cpu bottleneck right?

DEFINITELY! The problem is with the Bulldozer series, which are the 4100, 4150, 6100, 8150 etc.
By moving to the Piledriver (6300 for example), your problem should be solved.

I have a 7770 and had a core 2 duo, same thing happened, no matter at what settings and what res i play i would get 20 fps everywhere. Then i bought a i7 4770k and now i get 50-60 fps at 1920x1080 medium settings with ultra textures and sweetfx.
