THE MARKET FOR HIGH-END, enthusiast-oriented motherboards is presently dominated by NVIDIA chipsets. With few exceptions, the nForce4 has run the table for nearly a year, but that might be about to change. The recently announced Radeon Xpress 200 CrossFire chipset is finally poised to offer an alternative to SLI, and several mobo makers are lining up with boards based on the ATI's new core logic.

The first CrossFire board to become available in North America is DFI's LANParty UT RDX200 CD-DR. Designed by Oskar Wu, creator of the legendary Abit BP6, the RDX200 pairs ATI's CrossFire chipset with a myriad of extra peripherals, enough BIOS options to satiate even the most demanding overclocker, and DFI's usual dose of LANParty flair. The RDX200 is also the only Socket 939 CrossFire motherboard that's certified by ATI. Can its features and performance compare with the high-end nForce4 boards already available on the market? Read on to find out.
