A friend of mine has this XFX 7800GTX graphics card that has recently died. He reckons the "tiny little chip with 4 pins on each side" has fried or something. Anyway, before we waste time/money sending it to me to see if its repairable, we were wondering how the XFX warranty works. He only got this card like 2 months ago on ebay (used), so we dont know when it was purchased (but dont XFX have lifetime warranties?) Reckon we can RMA it? Thanks a lot. PS, he only has the card on him. It didnt come with box/accessories.
