OCC has published a new review on the Sapphire HD4850X2
Viewing your HD content has never been easier with the addition of support for four different monitors at one time. The last card I have seen to feature four DVI outputs was the Asus EAH3870X2. If you have plans on using this card with an HDMI output you can with the supplied DVI to HDMI dongle. To further expand on the HD aspect of this card, Sapphire has included an accessory pack that includes several suites of software from Cyberlink as well as a licensed copy of the latest benchmark from Futuremark. With pricing suggested in the $350 range, this card is right around the price of two separate HD4850 cards. If the Big Dog HD4870x2 is a little rich for your blood, then the Sapphire HD4850x2 will fit both the price and performance requirements for the vast majority of the public. The performance was a surprise.Sapphire HD4850X2 Review
