CrossFire Xpress 1600 Motherboards from DFI, Asus and ECS
 

The DFI RDX200 CF-DR, Asus A8R-MVP and ECS KA1-MVP motherboards performed at near identical levels in all of the benchmarks we ran. Overall, it is impossible to declare any one CrossFire Xpress 1600 based motherboard "faster" than another. Due to the fact that AMD's Athlon 64 processors feature an on-die memory controller, and we used the exact same CPU, memory and drives build up our test systems, similar performance was to be expected.
