Should I upgrade CPU or GPU?

Hello people! Next month I'm travelling to USA and was thinking on upgrading either my CPU/MoBo/ram or only my GPU. My current specs are:
-AMD FX 6300 Black Edition.
-ASrock 960gm-vgs3 FX.
-(x2) GSkill Ripjaw 4gb ram module.
-EVGA GTX 750Ti FTW.
-XFX Pro Ts 550w 80+ Bronze.

I was looking at buying a i5 6400 CPU, with a z170 MoBo (from ASrock, as I want to OverClock the new non K Skylake CPU with Sky Overclock), 8 GB ram ddr4 and a CPU cooler for the OC.

For GPU, I was looking at a with 4gb+ vram of the GTX 960/r9 380/GTX 970/r9 380x/r9 290 or any GPU for 350 USD at least.

Which would be better to upgrade, my CPU or GPU (in mobas,mmorpgs, AAA games like GTA V and others)? What GPU do you recomend I get for around 350$? Or what CPU/MoBo combo do you recomend I get, in case upgrading my CPU is better? Thank you!
 
Solution
I'd choose a GPU upgrade over a CPU upgrade.

You'll have a CPU bottleneck, but your gaming experience would be much better with:
FX-6300 + GTX970
than it would be with
i5-6400 + GTX750Ti.

If you kept the GTX750Ti you'd just have a GPU bottleneck most of the time instead, but on average much lower frame rate than the FX+970 combo.

Other:
1) Future DX12 games will use your FX-6300 better.

2) Some games have minimal or minor CPU bottleneck (in your scenario)

3) You can overclock the FX if you haven't already

*I'll give an example below..

Examples of CPU scaling:
http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/57615-amd-vishera-fx-6300-fx-4300-review-12.html
*Note that even with lower performance the FX-6300 still gets 50FPS in Skyrim, and with a few tweaks (and official and non-official patches) it can maintain 60FPS most of the time.

Again, just an example.
(and Dirt 3 has minimal CPU bottleneck, whereas Deux Ex HR does but the frame rate is still very high so it's not that big of a deal)

Example of minimal CPU bottlenecking:
http://www.techspot.com/review/645-tomb-raider-performance/page5.html

The FX-6300 would rarely be a bottleneck so upgrading your CPU would be nowhere near the huge boost upgrading the GTX970 would be.

*In reality, you'll sit somewhere between these examples depending on the game, but I doubt I can find a game that would work better with the i5/750ti combo over the FX/970 combo.

Hope that helps.

Thank you SO much Photonboy! Both of your answers were very helpful and full of data to help me decide. My question is, would you recomend a 970 above all else graphics cards in that price range? If so, is the 970 still manufactured with the vram issue it used to have? Would a r9 380/380x/390 be a better choice? Thank you!
