Hi folks,

Currently playing TW3 on my GTX 750. It's an SC Evga version, and I have not tinkered with it in any way. Get around bout 35-40fps on Low preset, 1080p.

My GPU usage is pretty much at 99% all the time (except when I go into the menus for example) cause I never ever reach the frame cap of 60fps.

Now, my question is, when I monitor my clock speeds, temp etc with Nvidia Inspector, it seems like the GPU doesn't sustain its boost clock rate at all times. What can be noted is that whenever I enter the inventory menu or map menu, and exit, as the temperature has dropped slightly the clock speed will go back max to 1359.

Also, one thing I have noticed is that my GPU temp NEVER breaches 80C...it stops at 80C and 63% fan speed.

Is there any chance the boost rate is connected to the temps? Is 80C an internal limit? Not that it matters much, but I do feel that for example at the max boost speed of 1359MHz and a slower speed such as 1280MHz, there is a difference of a few frame rates.

Assume I clean out my card (I know, it's a sin, dust and all that), and my temps go lower, would it be possible to maintain a boost clock all throughout? Or is the temp/fan-speed not related to the boost clock at all? In which case, what determines the clock speed? (Note: Game is such that my GPU is at 99% all the time basically, so that shouldn't be an issue)

Thanks!
 
Edit: Also, is there any major danger if the temperature is sustained at 80C for prolonger gaming sessions? Will it make the card die very much faster, or is it still acceptable?

Is there any danger to the hardware of my PC if the card is always at 80C when I am gaming? Or is this part of the design and nothing to worry about?

What do you mean by power limit, and what does this do?

Also, from 63%, assume I increase to 65%, what happens? Won't it be such that inevitably a few months down the road the same issue will crop up?
