I still vote for the ASRock Extreme4 but the Biostar is only $95 so if price is important you'll be able to save some money with the Z68 (even though you'll lose a decent number of features).
EDIT: You can't really crossfire with the Biostar board as it uses the Z68's chipset PCI-E lanes for the second PCI-E x16 slot which in turn makes it a 4x slot electrically. Latency also goes up to unacceptable levels which would make micro-stuttering horrible. In summary, if you're not going to crossfire ever, it's a decent board.
