Anyway, I haven't cracked one of those open, but the concept should be the same *for the most part*. However, the XFX card is liable to have thermal pads between the video RAM and the heat sink. If it does, then the main difference you'll be dealing with is that you'll need to be sure those are still in place when you put the cover back on. Also, you'll need to remove all of the screws along the top and the back of the card. A final possible difference is how the fans are connected. May be that one is plugged into the other and the other is plugged into the card, so you only have to deal with one cable, but it might be more complicated than that. But I doubt it.
As for putting the stickers back on: that'll depend on the glue they used. Sometime they use glue that damage the stickers if you attempt to remove them.
I won't pressure you into voiding your warranty. The only thing I can say is that I've replaced the TIM on my card (again, different manufacturer but the same card design), and it wasn't difficult.
