The Leadtek SLI platform shows its best in the second test, being at least no slower than the RADEON X850 XT Platinum Edition. It is sad 3DMark is just a synthetic test rather than a real game, but anyway the fact is the two Leadtek WinFast PX6600 GT TDH cards are faster here than top-end single-GPU solutions.

There’s an astonishing 30% speed bonus overclocking gives you in the “eye candy?mode. Well, the Leadtek kit is as fast as the GeForce 6800 GT even at its default frequencies. As for 1280x1024 resolution, the non-overclocked Leadtek solution competes with the GeForce 6800 Ultra there.

The third test is the most difficult one, containing numerous sophisticated pixel shaders. Yet even here the SLI platform competes with the RADEON X850 XT Platinum Edition in two resolutions out of three. Unlike in the first two tests, overclocking is of no effect almost.

Leadtek’s SLI solution isn’t disappointing in the “eye candy?mode, either. Outperforming the GeForce 6800 GT, it is even with the RADEON X800 XL in 1024x768 and slightly behind it in 1280x1024. Like in 3DMark03, the high overall result of Leadtek’s SLI kit is fully confirmed in each subtest.
