Better CPU = Higher FPS?

I'm trying to get the most out of my graphics card which is a Radeon XFX 7850 1GB core edition. However, I feel like in some games my CPU is bottlenecking it pretty bad. I notice it mostly in multiplayer games such as BF4 or MMO games. Even some single player games when there are a lot of characters on the screen at once. I know that games like BF4 are CPU heavy especially in multiplayer when you have a lot of players.

The CPU I'm currently using is an AMD FX-4130 black edition clocked at 4.1 ghz. If I join an empty BF4 server and turn the graphics settings on ultra I get about 70 - 80 fps. If I lower them slightly to a mix between high and ultra I get between 80 and 100 fps. But when I join a full server, no matter what the graphic settings are on, I usually get between 40 and 50 fps. Sometimes it will jump to 60 but then it drops right back down. It also doesn't matter if I join a server with 24 players or 64 players. It always sticks around 40 to 50 fps in populated servers.

My guess is my CPU is the problem here. I know that my graphics card isn't the greatest but I should still be able to get a minimum of 60 fps on low to medium settings with it when in multiplayer. I'm thinking about upgrading to the AMD FX-8350 and wanted to know if I would see a performance increase or not. Any help would be appreciated :)

PC specs:
OS - Windows 8
Mobo - ASUS M5A97 R2.0
CPU - AMD FX 4130
Graphics - Radeon XFX 7850 1GB core edition
Ram - 8GB 1333
HD - Toshiba 1TB & WDB 500GB both 7200rpm

Thanks for the replies everyone! Yeah I know 1GB GDDR5 is low for vram. However I'm only running at 1600x900 resolution. Lowering the resolution doesn't help my fps at all which is why I figured it was the CPU. I think I'll upgrade my CPU first then look into a new graphics card with more ram.

While I think your CPU is part of the problem I also think your video card doesn't have enough memory. I suggest instead of guessing why not collect a log of data using HWiNfo64? You can use the sensor to log to collect data while you are playing to get a better idea what's going on while your playing. All you'll need to do is start it before you start playing and stop it once you're done. Then open the spread sheet and look at your utilization for CPU, GPU and memory.

Get the FX 8320.
If you are still getting low FPS, then it may be your GPU doesn't have enough VRAM. You can alleviate this by playing on High (I cant notice the difference between High -> Ultra even if I tried) or by getitng a GPU with more VRAM. I would look at the R9 270 with 2GB of GDDR5.

I upgraded from an AMD FX4100 to an AMD FX8320 and overclocked it to 4Ghz. The games which use more than 4 cores showed good improvement. Battlefield 4 will use more than 4 cores and the multiplayer side of Battlefield 4 is quite heavy on the CPU so i think you would benefit from a CPU change.
BUT your video card as the others have said has only 1gb of video memory and as this chart of Battlefield 4 frame buffer usage shows it's not enough.
