The last few years, video cards have pretty much been running under similar thermal envelopes and power requirements. This is because both ATI and nVidia knows the limit on what they can reasonably get away with using a stock cooler for acceptable fan noise to alleviate heat and power consumption. So while having a longer warranty is always better, it's not any more important now than it was three years ago.
As DaveSimmons says, it'll die within the first month (or first few months) or it'll last pretty much years.
Having bought well over 10 video cards in the last 5 years (for friends, family as well as self) I can say that I've only had one die on me and that was an X1900XT within its first month. The rest have been going strong. Even if some of the older systems are way outdated at this point the cards still work fine.
So while I would always choose a card with longer warranty vs one with shorter warranty if prices are similar, I'd go with a card with lesser warranty if it was noticeably cheaper.
