Hi,
4 months ago I bought a Gigabyte 7800XT. It was wonderful, I had no problems with the card. Today I was doing some basic stuff on my desktop, browsing and stuff, not even playing, then suddenly I heard a pop sound, my screen went black, and I started to smell some burnt electricity smell. I immediately unplugged my PC, and smelled out that the GPU was the source (the exact location of the source of the smell is around the power connectors).
Am I right to guess that this is at this point, probably irrepairalbe? Will the store take it back under warranty? I didn't set any overclocking, I monitored its temperature while gaming and it didn't go higher than 65°C. I bought a 850W PSU just to be sure that it was enough, so it surely has to be some internal error, right?
