You should be fine with the box. I've never had to redeem it, all my XFX stuff still works.
I derped somehow and ended up frying it or something. I'm not sure if it's broken, but I'm 90% confident it is, you see, I had to remove my motherboard, graphics card, and sound card when I installed my heatsink because it's huge and barely fits in my case.
I set my graphics card on my carpet and I'm guessing it got friction somehow and shorted it out or something. When I installed it when I was done, the fan would go on full for 1 second, go to like 20, full, then 20 while my screen is blank and then it would just go on 20 or so and not show anything. HDMI, DVI and VGA don't work.
What's your professional verdict?
