Gaming at 2,560x1,600
We benchmarked the two machines at a 30in monitor's native 2,560x1,600 resolution, and one will need at least this kind of screen to put the onus on the powerful graphics subsystems.

The
tables are turned, just, in
Battlefield: Bad Company 2, as the Radeons sneak ahead. Both machines
deliver smooth performance at the 2,560x1,600 setting.

Perhaps the most popular game at the moment, Call of Duty 4: Modern Warfare 2 is a DX9 console port that runs very well on mid-range hardware. Doubling up with two very high-end cards leads to over-the-top performance: the Scan system's minimum frame-rate is 128fps.
