Futuremark released 3DMark Vantage, on April 28, 2008. It is a benchmark based upon DirectX 10, and therefore will only run under Windows Vista (Service Pack 1 is stated as a requirement) and Windows 7. This is the first edition where the feature-restricted, free of charge version could not be used any number of times. 1280×1024 resolution was used with performance settings.
The HD7770 falls in ahead of the HD6790, scoring 13,329 points in single card mode. The AMD HD6870 is way out ahead this time, scoring 17,023 points. In Crossfire the performance scaling is very strong, with both cards scoring almost 25,000 points. This places the dual card configuration between the HD6970 and Nvidia's GTX580 which scores 26,342 points.
Crossfire results are quite good as author said compared gainst more expensive 7950. much like the 5770 I owned, I had two and it was really good.
