I don't know if this can end up killing my graphics card but earlier today I had a graphics spasm in my Mac things started changing blocky colors. This happened on my Snow Leopard side too and than the next thing I remember is my gtx 470 being dead and the company being nice enough to send me another gtx 570.

I never told them that could have been the reason my gtx 470 had died. Could have all been coincidence but I just have to ask does anyone know if Hackintosh can actually harm you graphics card over time? I don't see why it would, but that graphics spasm thing I have had happened to me rarely happens. It has only happened twice to me. Once on Snow Leopard, (Next thing I know my gtx 470 is dead, could have been coincidence tho) and than now it has happened to me with my gtx 570 earlier yesterday actually since its 2 am now. I would say it did it about maybe like 4pm yesterday. I had to end up shutting my Mac down the incorrect way because the blockyness just went everywheres.
