SourceASUS has a 3-year warranty on the EAH4890 HTDI/1GD5. Given its much lower running temperatures than reference cards, I don't imagine you will have much in the way of heat-related component failure. However, those 3 years can be critical compared to some of the competition having only a 2-year warranty. Ignoring the additional capacitor on the card, this card really just has that stellar heat sink to separate it from the horde of reference Radeon HD 4890s out on the market. What I don't understand is why ASUS didn't launch this card with much higher card-clocks like many in their TOP series. I was able to run the card at 950/1100 all day long, so why not launch the card at 925/1000? Regardless, you as the end-user should be able to easily hit 950/1100 with Catalyst Control or Smart Doctor.
