Though not the fastest, the flashiest, or the least expensive system in this roundup, the Velocity Micro Gamers' Edge DualX ($5,759 direct as tested) is the balanced middle child that shouldn't be ignored. The DualX is a solid SLI system with an understated grace and plenty of speed. For the price, you get a whole lot of good features: a 2.6-GHz Athlon FX-55 processor, dual nVidia GeForce 6800 Ultra PCIe graphics cards linked with SLI, a fast 20-inch 1,600-by-1,200 native resolution LCD monitor, and the sonorous Creative GigaWorks S750 5.1 speakers.
