Problem with High-end Game Stuttering (Possible CPU Bottleneck)

While playing BF4 (Battlefield 4) and other high-end games, my CPU is often 80-90%, and BF4 it uses 100% sometimes, and in BF4 I get framerates that are a bit low. In some heavy multiplayer maps I tried medium preset and Ultra preset and I still get around 40 FPS and dips down to 20, and every few seconds it freezes for about half a second and stutters, it's a bit hard to play and frustrating. I checked task manager and resource monitor my CPU is all most at full usage, and all I usually run in the background is non-heavy stuff such as steam, skype, etc. My RAM is fine, never use all 8GB and usually don't get close. I think my CPU is a bottleneck. Some people's PCs with a similar or slightly worse GPU can easily get 80+ FPS on BF4 on High, and 60+ on Ultra.
Here are my specs:
---------
CPU: AMD Phenom 965 BE OC 3.7Ghz Quad Core 6MB Cache
GPU: AMD Sapphire Vapor-X R9 270X 2GB GDDR5 1050Mhz Core 1400Mhz Memory 1280 Processors (New)
Hardrives: 500GB Samsung 7,200 RPM HDD, 1TB Seagate Barracude 7,200 RPM HDD.
RAM: 2x4= 8GB Ripjaw Gaming Series G.Skill RAM at 1333Mhz
Motherboard: Asrock 880G Extreme 3 Am3
PSU: Rosewill Capstone 80+ Gold 750W (New)
Case: Thermaltake Overseer Rx-i Black
CPU Cooler: Cooler Master Evo 212+ Hyper
--------
I do have efficient Airflow and exhaust as well. My GPU temp is about 25-30C Idle, and 40C while doing videos and rendering, and 50-65C while gaming, usually doesn't go any higher. and CPU is 32-36C Idle and 40-48C Gaming rarely reaches 50C even under extreme loads including Prime95. I don't think it's a overheating problem. I have a 200mm front intake fan, and a top 200mm exhaust fan, and a back 120mm back exhaust fan. There is no dust either, this is a new case and components have been cleaned from awhile ago.

Thanks for the help!
 
Solution
Either get a 990 am3+ mobo and fx 8320/50, or z97 and i5 4690k. The am3+ is a dead socket but still a good one and the z97 offers current tech and broadwell support for later. My fx 6300 is always 80-100% used in bf4 with a hd 7770 and bottlenecked my r9 280.

It sometimes happens in other high-end games as well, if the graphics are set high enough. Also when I record high-end games the CPU can reach 100% most of the time and videos tend to stutter and lag behind, but when the CPU is not at 100% while recording the video is fine. I'm pretty sure my CPU is a bottleneck.

Good idea, I'm considering getting a new motherboard and CPU, but it's a very expensive upgrade and it's more considering just getting a new system after a few years. AMD Phenom 965 is a great CPU but it's from 2009, outdated architecture, not so fast cores now days, and it eats a lot of power. Plus it's over 4 years old for my system and it probably has degraded a bit.

Sorry for the very late reply, don't really have too much of a budget plan but probably something that is bang for the buck, or can run with an R9 270X very well and is futureproof.
