I was overclocking my eVga 7800GT CO last night using RivaTuner and I got a little too overagressive with the settings. I tried to run 3DMark05 when, during the middle of the first test sequence, I started to see artifacts. The sequence then froze completely, and my screen then flashed from a black screen to my desktop view, then back to a black screen, then my desktop, etc. After about 30 seconds of this, I reset the PC (which resets the card's settings back to the default 470/1100). I was able to watch a DVD afterward and play HL2 without any problems. Am I correct in assuming that my 7800GT suffered no immediate damage from my irresponsible experiment?
