"We said we would test the GX2 again once we obtained some updated drivers, and that’s exactly what we’re about to do right now. From a hotmail account this morning, we received the 174.51 drivers. The difference between these drivers and the last batch of 174 drivers we tried is that these ones actually installed!
Word is that the new drivers fix the profile issues that were present in the 173.67 release. While some people say SLI just wasn’t working in the first driver we tested, the issues seem more related to profiles."
