What is the temperature when does my Gpu start to break?

[Guest]

So my card is Nvidia Geforce Gtx 780 oc Asus Direct CU II.

So right now it runs about 80°C overcloked, so is there room to overclock more?

Your temps are fine, you can go as high as 85C though.

Infact most gpus can sustain as much as 95C but to be on the safer side its better to stay below 85C.

Having said that, my laptop's gpu has been running at 90C on a 200 Mhz overclock over stock speeds for more than a year now. And it stay stays at 100% load almost 16hrs everyday crunching BOINC.
So you should be fine.
