Yes Win7 x64. I called AMD tech support and was told that it will not work. The IGP is a 4000 series and my card is 5000. So if it did work, it would revert to the lowest gpu and be useless. He said that it would work if I had a 4000 card. I think it is a marketing thing myself. The 4250 IGP is good by itself if you don't have a graphics card or want it for a HTPC. I am happy getting the PCIE 2.0 on it for my HD 5670, it is working really well on my games.
