Default New User to GPU computing. I have questions

I currently have just posted some results to the GPU72 website and I am just starting to get this project running. I have an i7 intel cpu (Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz) and a GTX 750ti GPU and I'm running windows 7 64bit with mfaktc. I want to know how I know that my GPU is being used fully or at least most of the way. Is there a way to tell what percent of the GTX 750ti I'm using? I'm running one mfaktc on my computer. thanks.

There are quite a few possibilities, but Tech Power Up GPU-Z gives lots of information about GPU, and has a page of graphs displaying usage, temperature, frequency, etc.

Wow, that's a nice utility. It says I'm having some performance capping done, at least that's what I see. Is this normal with GPU computing? I've attached a screen print.

My cards are too old to have the performance capping feature, so someone else will have to answer. Are you also running Prime95 on the CPU? If so, 98% GPU usage is pretty normal, in my experience.

Seems normal from my point of view.
98% GPU useage with 1320MHz (boost clock, default clock is lower) and normal operating temperature.
I believe the performance cap reasons of the newer cards are: temperature, TDP and Voltage.
In this case no higher boost clock can be used (even though there is TDP and temperature headroom, because that would require a too high Voltage (Vop).
