My current cpu is the AMD Phenom 2 X4 955 BE. I am running it together with the Asus GTX 680 DCUII.

My problem is that even with Nvidia updating drivers to offset load on the cpu, I am still getting 30-40 fps in certain areas on the BF4 Multiplayer Maps eg. Hainan Resort on low, although peak is 90 fps in other areas on low.

In Minecraft with shaders, the city that the server I am on is building drops the fps a lot, but stays above 60 fps without moving. When moving, chunks get loaded and it drops to 30-40 for quite some time before stabilizing.

After much research I can only conclude that my cpu is bottlenecking the gpu, but I would still like a final verdict on it, because I am planning to get the i7 4790 non k version; I want to know whether it is worth getting it or that my problems can be solved without hardware change. Overclocking the AMD CPU is not an option; I didn't see any improvements. I would also like to know if I should put off the upgrading for newer cpus with better architecture that might be released next year.

That's because the i7 is 100Mhz faster (3.9Ghz vs 3.8Ghz). At the same clock speed the i5 and i7 have identical single thread performance.

Your CPU is a bottleneck for this GPU. You can either upgrade the CPU, or turn all the settings to ultra. You won't see almost any difference in performance in both low or ultra. If you can be satisfied with 30-40 fps on ultra on *some* areas with 90 on most of them (most people would be fine with that) then I even don't really see a reason to upgrade ;)

What is your processor speed? While you can't the basic design or age of the CPU you can get a decent performance boost by OCing it to the max. I have an Phenom II X4 980 @ 4.1 on air paired with an ASUS GTX 670 Direct CU II and it does quite well in most games. If your 955 is a C3 stepping you should be able to get another 600 Mhz out of it at least with a good aftermarket cooler.

Problem is I have tried, and it didn't give any significant boost, at least not over 60. The stock speed is 3.2 GHz, and I could get it to 3.8 but it BSOD after a while playing BF4. I have a aftermarket cooler, but point is it didn't help.

Well the i7 is more for the single core performance...see this game, Kerbal Space Program runs its physics on one thread, and someone compiled cpu benchmarks for it showing i7 as the top here.
http://forum.kerbalspaceprogram.com/threads/42877-CPU-Performance-Database
Still the i5 4670k is really close, so I'll have to see if it is worth more.
Edit:
Also that particular benchmark is using the Ares 2, which if I am not wrong is 2 7970s. I can't get a straight answer as to the performance increase by changing the processor with a gtx 680.

Thing is...it stays at 30-40 fps at the lobby of Hainan Resort, no less, so firefights become really annoying there. It goes up till 90 at spawn on low, which doesn't matter unless I am being attacked at base. Also Minecraft without shaders is over 200 fps without graphical shaders and chunk loading does not affect it, but with shaders it pushes it down to 60 fps with <60 when moving ie. loading chunks. The final question is whether it will be worth the upgrade to an i5 or and i7.
