Techreport gives us the lowdown on four P67 motherboards from the big three...and Intel.
What follows is a pretty comprehensive comparison of all four mobos. Recommended reading if you looking
to upgrade right now. Its safe to say that you shouldn't even be
looking at P55.
The Asus mobo would be my pick...
...slick UEFI implementation, stellar layout...even a bluetooth transceiver is included.
For me, going from X58 to P67 would be quite the downgrade...
...but I have to admit,
Sandy Bridge and P67 makes for one truly kick@$$ platform.
GG Intel.
