Greetings,I have tried to find does GPU overclocking really reduce it's lifespan if voltage isn't raised,and temperature stays normal.I found mixed answers so I am posting the question here.I am going to get HD 7850,then plan to overclock it to 1050/1250 at least(people got it to 1200/1400 winouth voltage increase).Card is very cool,around 60C max load.Thanks in advance.
