Just ordered a 2nd 5770, I got one a few years ago, and they're the best watt->mHs (2.25) i could find.
A lot of mining info is spread out and I never know if certain info is current.
Anything I should expect? Is crossfire needed or not? What kind of temps should I be lookin out for?
Thanks much in advance.
All of what you ask is dependent on cooling,power supply and current setup.I believe a 5770 is rated at 108 watts each thus add about 150 watts for your current system and wattage for your current videocard might give you a ballpark figure.Crossfire shouldn't be required and actually gives you less rates.General rule for temps is keep it under 80 C or you could be looking for a new videocard in under 2 months when the fan is broken.[notice I didn't say if]
