ATI Radeon HD 5870 + 5850 Crossfire – Mixing Video Cards

3DMark Vantage

3DMark Vantage is the new industry standard PC gaming performance
benchmark from Futuremark, newly designed for Windows Vista and
DirectX10. It includes two new graphics tests, two new CPU tests,
several new feature tests, and support for the latest hardware. 3DMark
Vantage is based on a completely new rendering engine, developed
specifically to take full advantage of DirectX10, the new graphics API
from Microsoft.

The Extreme settings were used for testing, so a resolution of 1920×1200 was used.

Benchmark Results: In
3DMark Vantage we see the mixed CrossFire solution being just behind the Radeon HD 5850’s in CrossFire once again, but not by much.
