Alienware has already released a gaming rig with NVIDIA’s top-end GTX 280 graphics card, but if that’s not your fancy, we suggest that you look at ATI’s Radeon HD 4870 X2 as well. This card offers 2.4 teraflops of graphics power, is available in the company’s Area-51, Area-51 ALX, and Aurora desktops, each of which also available with dual HD 4870 X2 cards in a CrossFireX configuration. To be able to run a computer with that card, however, you will also have to change the power supply to 1200 watts.
