Myself I have used PNY for years, always been very reliable, until this last year. I have returned XLR8 video cards twice to them and then they failed again. However it is passed the 1 year mark now and they are denying my 3 year warranty registration. They used to be very good, but now i think they are 100% crap, I still have my old cards from 10 years ago and they work fine still, but these new things are junk in my opinion. I won't use their cards a gain, will choose another company like Asus myself.
sorry to hear that, I've bought 8800gt from PNY in the past for my friend and it still works. When purchasing parts my favorite manufacturers are AsRock and Asus
