Ok not sure if anyone else has told you this, but your benchmarking software is not working correctly with ATI CrossfireX configurations. I downloaded your latest build and ran the test and I use on-screen monitoring to see the GPU's usage and NovaBench is only using one GPU core out of 4 that I have. The other 3 GPU's set idle a 0% usage. I noticed you have this working fine for NVIDIA cards so what gives? Is NVIDIA funding your project? I have two HD5970's in crossfireX and only 1 GPU is used out of 4 when using your benchmarking software. My cards run perfectly fine and score good in other benchmarking software, yet this tool you have doesn't measure CrossfireX correctly at all. Try it for yourself!
