HardwareLogic posted a review on the Asus Rampage Extreme Motherboard

Every now and then, motherboard manufacturers will release a board specifically made for the high end market. Much like Intel's Extreme series processors, these extravagent boards throw caution to the wind and load up with as many features as possible, no matter what the cost. The last high end motherboard from Asus was the Striker II Extreme based on the 790i Ultra chipset and guess what folks, it's that time once again. Introducing Asus' latest luxurious creation, the Rampage Extreme featuring Intel's X48 chipset. This board overflows with awesome and takes high end to another level. The 'RE' provides native 1600MHz front side bus support, full x16 CrossFireX capability, up to 8GB of DDR3-2000 memory compatibiltiy, an X-Fi soundcard and the biggest bundle ever. If you like cutting edge, you'll love this review as I conducted both quad and dual core testing along with making use of those two PCIe x16 slots with 4870X2 cards in CrossFire. Oh yea! Read on to find out if this monstrosity can take the coveted crown as the best motherboard on the market.
