Computer Upgrades for Gaming (Advice Needed)

[Jordan25th]

Hi, I was wondering if anyone would be able to help me. First I'll list my computer specs and then show what I would like to upgrade. I've had trouble upgrading my PC before due to incompatible parts but any advice/recommendations would be great!

My Specs:
AMD-FX(tm)-4100 Quad-Core Processor 3.60GHz
8.00 GB Corsair 1600MHz Ram
500GB Hard Drive
Corsair 600w PSU
ASUS GeForce GTX 750 1GB

I would like to upgrade the Graphics Card firstly then upgrade the CPU. (Specifically an NVIDIA card because I like to use ShadowPlay)

Price isn't such an issue but I don't want something that is ridiculously expensive, just something that will run games such as GTA V, Arma 3, DayZ Standalone, Black Ops 3 etc. at a decent frame rate.

Once again any advice/recommendations are really appreciated.

Your FX-4100 is a bit of a weakling when it comes to good gaming CPUs. But it can keep up with far faster gfx cards than the GTX 750. But too much card will be wasting your money if CPU bottleneck starts rearing its ugly head. I'd recommend the GTX 950/960 or R7-370/R9-270X. One of these should make a huge difference in gaming for you.
