Also, you claimed performance was bad, now you claim performance was not bad.. I don't understand you Every driver has bugs.
So the purchase is sure futureproof.
But if one wants all features now, on modern hardware, then the best choice probably would be closed source nvidia driver with one of nvidia GPUs I recommended.
@Kano: Radeon VDPAU implementation is how many days old? xD Why do you expect it to be free of bugs, especially with Adobe Flash, that has Blue People bug with nvidia even now?
