Everyone knows that SLI systems will outperform those with just a single card. With one system costing over twice that of the other, we still want to find out if the lower-cost AVA Direct system is good enough for our game benchmarks, and then compare the performance to price difference between it and the Digital Storm Twister Extreme.

3D Games

The AVA Direct system has twice the minimum required performance for playing Doom 3 at super-high resolutions (above), even with anti-aliasing and anisotropic filtering enabled (below). But even with AVA Direct's admirable performance, the Digital Storm Twister Extreme still stomps it, especially at higher resolutions.

The Digital Storm Twister Extreme proves its worth in F.E.A.R., with double the average frames per second of the AVA Direct system at the game's highest settings. The AVA Direct system still exceeds "minimum playable frame-rates" by nearly 50% at the top setting, however.
