The best the 965 can do is a 270X or 760 without bottleneck.
OC'ed to 4.22GHz I was able to run my 760 to 99% (it never hits 100% with anything) in nearly every game.

A 960 and 380 will always have a level of bottleneck, as they are a fair amount ahead of the 760.

The R9 380 in some games will be bottle necked by the Phenom II x4 965 be processor. It actually bottlenecks some games with a HD 7970/R9 280X so it will surly bottleneck a faster GPU.

On this I speck from experience as I have the Phenom II x4 965 be OCed to 3.957 GHz and a HD 7970/R9 280X GPU in my gaming system. While I can play most games fine certain games need the graphics turned down to compensate for the weak CPU. Games like Crysis 3, Far Cry 3, Bioshock Infinite, Resident Evil Revelations 2, Battlefield 4 ect.

Hi dude, i was just reading your answer and i wondered if you could help? i just upgraded from an old pc, my new system has 8gb ram (1600mhz) amd x4 860 and a gtx 960 2gb.. yet for some reason i am getting 20fps on arma 3 and my old lower powered pc would get 30+fps. any help or advice would be greatly appreciated

Generally the weaker a CPU the better it is to pair it with an Nvidia card. Nvidia drivers tend to have less overhead and place less demands on the CPU than AMD cards (except in Mantle games of course). Radeon drivers were particularly worse in that aspect about a year ago but have improved in the last few releases. They still use more CPU resources than Nvidia drivers though and again, its more noticeable with an older/weaker CPU.

As far as your specific question, I used to have a Phenom II X4 955 oc'd to 3.6 Ghz paired with a GTX 670. That GPU is almost identical to the GTX 960 in performance. The Phenom II bottlenecked it a little, but it still performed pretty well overall.

Please start a new thread so that we do not take over the OP's thread. Thanks. But... make sure the settings are the same as they were on the old machine and Arma (any of them) is a very CPU intensive game due to the heavy physics used in the game. You can not compare one machine to the other unless the settings are the exact same.

Answer: Holy hell yes. The 960 and 380 don't mostly care for the CPU all that much, but a Phenom II at 3.4 GHz will bottleneck both GPUs a bit, maybe 25% at 1080p and probably not much at 1440p. Try overclocking it to 4-4.2 GHz and you'll be fine

While OCing the CPU will help, you will still bottleneck. I know this as fact because before I went to 16GB of ram from 8GB I was able to OC my CPU ( Phenom II x4 965 BE rev. C3) to 4.072 GHz (only 28 MHz from 4.1GHz) and I would still bottleneck with an XFX AMD Radeon HD 7970 DD version Oced to 965 core and 1675 memory witch are less powerful than the AMD R9 380.

in short OCing that CPU will not stop the bottleneck.

Hello everybody,
I reached this post because I own this cpu and I'd like to add a decent video card. Friends suggested me the 7970 or the gtx 760. So I guess this is the best place to ask.
But my favourite shop only have a zotac 760 for 180€ or gigabyte 750 ti for 130€.
I think that the gigabyte is a good one, i own the 970 G1 on another pc and I love it.

Do you suggest me to use this CPU with a Sapphire IPC-AM3DD785G mainboard and the gigabyte gtx 750 TI ?
I'd only use it to play games like the sims 4, cities skyline, probably dota 2 ..

thanks guys

Edit: It should not bottleneck, but i'm more worried about the mainboard than the cpu
