I just had an 8800 GTX OC PNY card fail under the 3 year warranty. They sent me a refurbished GTX 260. No Box, no paperwork, only the card in a bubble wrap. I emailed them about this and they jumped all over me and slapped their fine print on me that they were no way under obligation to provide a new card. I don't even know if I can register it. I don't think I can because they say my warranty continues from the first failed card.
Well - the refurbished card is bad after just a couple of days. It artifacts - and the clock speeds
of the card show much slower than they should be - and cannot be changed without failure. Example... core clock should be 576 - it runs @ 341. Memory is less than half its rated speed and so on.
Do not trust these people, dont know what they are going to do about this one yet.
