So I viewed both of my 7870s in GPU-z and noticed that my BIOS versions are different, but I don't find an updated BIOS for the Asus:

Asus: 015.021.000.002.000000
Sapphire: 015.031.000.000.000000

When I use the BIOS update tool in Asus GPU Tweak (basically Afterburner + GPU-z) it says my "system is up to date". There is no update for this I could find on the Asus site.

The specific card is an Asus HD7870-DC2-2GD5 v.2

Any suggestions?

Not from the BIOS unless it's capping your clock rate like the stock one on my 7970s does. You want to be really careful messing around on those, I reverted back to stock after some OC experiments because it was more stable.

No, not with Crossfire. However, I can get some higher clock rates out of the Sapphire.

I was just curious if I was missing out on some performance gains.
