While we're in the midst of reviewing a handful of AMD 890FX motherboards to go with your new Thuban-class processors, ASUS dropped us some photos to share of their top AMD 890FX motherboard in the works. As if the ASUS Crosshair IV Formula wasn't bad-ass enough, the even newer Crosshair IV Extreme motherboard (also part of the Republic Of Gamers series), topped the Formula with a Lucid Hyrdra 200 chip integrated onboard to enable multi-GPU configuration of either ATI or NVIDIA graphics cards - basically the holy grail of multi-GPU. Of course it's not a ball in the park as we've found out with MSI's Big Bang Fuzion motherboard earlier. However, drivers are steadily being churned out and we hope it has improved a good degree for ASUS to stake it out with this new Crosshair IV Extreme motherboard. There are other notable features too, but we'll let the few pictures below do the talking. Enjoy and save up!
