Upgrade from Non K Model to K Model for Performance

[Isaiah98]

Hi there

I have recently been interested in improving my PC performance in general. I was told not to bother with a I7 model as i won't be using photoshop or rendering.
My main question is should i upgrade from my Non K model CPU to the K model to overclock and will it make a difference. Games i play include Battlefield 4 , Arma 3 , Elite Dangerous just to name a few. My frame rates in Battlefield for example will be around 110 and 70 at crazy moments on Ultra. The main reason this was brought to my attention was because how much my PC struggled on the 3D Mark skydiver physics test.

Specs:
CPU: i5 4690
GPU: G1 Gaming GTX 980 Overclocked
RAM:16GB
Resolution:1920:1080

Please tell me if i've missed any essential information and i will add it ASAP.

No it will not make a noticeable difference. You would also have to get an after market cooler (and have a Z motherboard) to be able to overclock anyway.

Are the low scores on the physics tests for 3D Mark expected for any CPU aside from top end extreme models.

What numbers do you get, and why do you consider them to be low?

Well actually in regards to my score i have no others to compare it too but a reliable metric is the insane frame rate drops down from 120 to 30 when i enter the physics test.

Have you looked at what the physics test does? It will spawn up to 96 threads to deliberately overload the processor. It's a stress test that goes to the limits and beyond. If you return a metric like 6000, you are doing about as well as can be expected. I run a Xeon 1321v3 with 4 cores and Hyperthreading and score under 9000, and get serious FPS drops there too. That's what that test does.

Thank you
I was unaware of the actual function of the physics test other than it testing the CPU in particular. I also wasn't aware that it's goal was to overload the CPU.

Each one of those moving pairs of hammers is a thread, so as you withdraw down the corridor, more and more threads are spawned. If you have dedicated PhysiX it will handle some of the load.

I think 96 threads will stress just about anything.
