I wouldn't call a graphics card that packs in after a year or 2 normal because you pay good money for a graphics card that can do more than an average card eg: playing games in better detail etc... If it packs in after a year or 2 it really isn't worth the money compared to a rubbish graphics card that will last 5 years or so is it?
You misunderstood me. I was referring to the percentage of graphics cards that pack it in out of any batch/brand. These things die and get replaced...I'd like to know how many ATIs get replaced as opposed to Nvidias. If we could get some numbers we'd actually know if there is something to this speculation.
