My card here PNY XLR8 Enthusiast Edition VCGGTX580XPB-OC GeForce GTX 580 (Fermi) 1536MB was bought from a friend i no longer have contact with anymore 2 and a half years ago. On the page it says:
Warranty
Limited Warranty period (parts): Lifetime
Limited Warranty period (labor): Lifetime
Can i still try to get a replacement card from them even though i don't have proof of purchase since it does say lifetime so the purchase date wouldn't matter?
