Will 80c plus temps limit the life of my 780?

I recently rebuilt my system and went from an 8350 to 4770k and also upgraded to a 780 from a 7850. I have overclocked my cpu, but not my gpu. I have the EVGA Superclocked 3GB 780, with refernce cooler, I love the look but I'm wondering if the consistently high temps during LONG gaming and streaming sessions may limit the life of my gpu, I am considering SLI 780 in the future so I need this card to last. EVGA has a great policy allowing my to switch the card out for the ACX cooler design, I know that card is running almost 20c cooler in all situations except idle. As superficial as it is, I have a windowed R4 and my pc is seen alot and I lvoe the look of the green le and the card itself. That said, longevity over visual appeal, is it worth trading it in for the ACX design for no charge? My temps are always 80c when playing Titanfall, BF4, skyrim. Thanks guys for the opinions!

You should have read that article you quoted more carefully. The throttling temp of 780 is 80C and when the card doodles around that temp, throttling takes place and performance decreases, do we want...

I am talking abt maximum 75C, and thats not icy for me. Mathematically, every degree increase results in a life shortening, we may or may not encounter that(upgrading, discarding before EOL), but yes, mathematically it does affect.
Talking about icy, non reference 780's run very cool. so 75 is no in no way icy.

I stand by everything I said, because it's all absolutely true. 75C is 20 below TJmax for the card, which is icy by any reasonable standard. The way HardOCP reviews video cards is completely inane, and for every bad example, there's a perfectly reasonable counter-example:
http://www.anandtech.com/show/6973/nvidia-geforce-gtx-780-review/19

But all of that is neither here nor there, OP wanted to know if there would be any effect on longevity running the card at 80C versus some lower temperature, and the answer is an unequivocal "no."

You should have read that article you quoted more carefully. The throttling temp of 780 is 80C and when the card doodles around that temp, throttling takes place and performance decreases, do we want this? Absolutely NO. Its Tj max is the temp where your system will shut down or something BSOD like will happen. Anandtech review was for the reference card and I clearly explained mine was for "NON REFERENCE CARD". Means if he gets a good cooler, problem is solved. Also, those temps on the review are with furmark, which is hard hitting on the GPU than any game we play, and OP is getting 82 while gaming.
As for the life with temp thing, I also completely stand by my words and I will say, because I know, that every degree increase leads to a life shortening of the component. However small decrease it may be.
The life of an electronic device is directly related to its operating temperature. Each 10°C (18°F) temperature rise reduces component life by 50%*. Conversely, each 10°C (18°F) temperature reduction increases component life by 100%. Therefore, it is recommended that computer components be kept as cool as possible (within an acceptable noise level) for maximum reliability, longevity, and return on investment.
*Based on the Arrhenius equation, which says that time to failure is a function of e-Ea/kT where Ea = activation energy of the failure mechanism being accelerated, k = Boltzmann's constant, and T = absolute temperature.

Yea, I ended up reading that entire article as well and they do state the cards default throttle is 80c, and show it throttling at 84c. I guess I'll go for the ACX cooler while I still am under the EVGA 90day switch. The much lower temps will make me feel better and I can retest everything on my end as well and see if I was throttling the reference 780 during the benchmarks I ran. Thanks for all of your input and opinions which led to a resolution.

EDIT: Also, I'll report back my findings to help anyone that may want the info to understand where their 700 series card is throttling and if their temps are good.
