Maybe you used it too little

Thirty-eight seventy, right?
who cares what happened? .. RMA it if you possible can .. while it is still under warranty and a good performer; especially as you say it is 10 months old
NewEgg *exchanges* most products for a year .. if not .. RMA it to the manufacturer
- what Brand is it?
My ASUS 4870/1GB also died - the one with the reference cooler after a few weeks and i got another 4870 to replace it with a different kind of cooler .. also ASUS - but now 'Dark Knight'
4870 is significantly faster than 3870; probably faster than 3870 Crossfire and 4850 is a little slower than 4870
- 4870x2 is significantly faster than 4870 and is at the top of the AMD graphics card lineup
