me card is death yes or not ?

NO DONT USE THAT ONE.
You can try the Gigabyte 7970 one, since I had a Gigabyte 7970 and I flashed a Gigabyte 280x bios on it and it worked in the past. NO IDEA if flashing an 7970 bios on a 280x will work. You might brick one of your bios. Do it at your own risk. You got dual bios at least.
