I want to buy a 7870 and crossfire in the future, but i can't handle massive microstutters smile.gif

Not that I have noticed. I play bf3 and it runs great with these in crossfire. smile.gif

Yup same like mine smile.gif its a bug from reading voltage I am sure now. Even with GPU-Z monitoring sensor sometimes it shows 1.84volt biggrin.gif I hope HD7870 soon release new bios or Afterburner soon release fix version for HD7870.

Just curious what wattage your power supply is? I've got a Sapphire 7870, thinking about putting another one in down the road.

It is really low power usage, so for CF HD7870 maybe 500watt with pure power and enough +12volt rail amps is enough smile.gif for accurate info you may ask Navit since he uses CF of them wink.gif
