We got close to two Radeon HD 2900 XT cards and we can confirm that the cards scores 13,100 on a Quad core QX6700 processor.
We are talking about 3Dmark 06 and the default resolution scores. In Shader model 2.0 it scores 5,056 while in HDR/SM3 it scores 6,245. The CPU score is 3,658.
The 3Dmark 03 score is 45,000 which is not that bad, but two Geforce 8800 GTX in SLI can do more than 50,000.
Just in case you wanted to know how two of these work together. More on this subject soon.
