If you want top performance, look no further: Alienware’s $3699 Aurora 5500 is currently our record-setting desktop. This high-end gaming system scored the highest mark yet–110–on our WorldBench 5 test suite, and, running our graphics-testing games Return to Castle Wolfenstein and Unreal Tournament, it posted the second best graphics speed we’ve recorded–an average of 283 frames per second. The Aurora’s muscle stems from AMD’s flagship 2.6-GHz Athlon 64 FX-55 processor paired with dual 160GB hard drives in a RAID 0 array and a 256MB ATI Radeon X800 Pro graphics card.
