Official or unofficial solution... Fact is, SSAA works with nV in DX9-11 but it doesn't with AMD. This is probably more important than PhysX or SSAO for most gamers.
More flexible SSAA is the reason I probably stay with nvidia and even with ssaa I'm already often CPU limited (even with SSAA) with my CPU and res. (these MSI GTX 580's are clocking near 1 ghz)
If AMD would follow nVidia and gave us SSAA in dx10+ I consider (but even then, SSAA is a lot more flexible with nV, i have a lot more possibility's to tweak/use).
