what is the treshold temperature for 6950? is it safe to run this card 7/24 at 80-88 celcius / 175-190 Fahrenheit? so far no problem but is there any risk?

Crunching 24/7 already stresses hell out of the card. I recommend 85C at max just to have a tolerance interval. Although the card throttles at 120C, I consider going above 95C as slightly dangerous.

You will be fine. Your card architecture is built to handle more stress and heat than that.

My HD5850 runs at 46C, using the 3 fan aftermarket cooler. But the HD5970 runs at 77C with the stock cooler.
Go away, I was asleep

Have been using the 6990 for about a week now. Overclocked with stock cooling... runs anywhere between 92 to 101 C under full load.

It's a hot card.

As noted, the card is thermal rated for that heat range. However, if you aren't comfortable with that, a program like the latest MSI Afterburner will allow you to create overclocking and fan/heat profiles to better regulate your temps. The program works with cards other than those from MSI. I personally like the interface and small footprint of the program.

How is your Case airflow? Just got a 5870(replaced a 4850) a couple weeks back and my GPU Temps were upper 70c/80% Fan Speed with too much Fan noise for my small apartment and the heat within my old case(Xaser III) caused my CPU to overheat. Bought a new case(Zalman Z9 Plus) and now my GPU Temps are 69c/57% Fan Speed making for a much cooler CPU and quieter system overall.

you're fine running around 100 silicon wont get damaged until much hotter.

hotter cards just use more power. my 5870 runs at 90C/45% fan load

just a quick off-topic question, how long does each WU take on your 6990s either stock or OC?

6990 oced to 930/1380 will typically crunch between 59 and 69 seconds. Ive had some inconsisent results though. Ill be adding another 6990 next month... Hoping that the drivers are a bit more stable by then. 3rd week in and already having wierd issues with CCC. At stock bios selection 2, this card will most likely perform very similar to a 6970 per WU... It just has 2 of them per card.
