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]

If you believe this post has helped,please donate-

Fans are at 90% Under 80c?  Hmm, MSI Afterburner has me at peak 87, but thats 77 in CCC I'm not sure which to pick, but in either case I need to lower it if I'm gonna put another card in.

I have a CoolerMasterHAFhttp://www.coolermaster.com/product.php?product_id=6653, but I'm only running stock cooling.
