Techpowerup has reviewed AMD's Bulldozer with the new Windows 7 patches, but unfortunately they do not seem to speed up improvement much.
Applying the patch to fix a core schedule bug in Windows 7 also didn't improve performance much, and it is doubtful Windows 8 will change things for better. Either way, AMD should have given us a competitive new architecture some time ago, and now that they finally did, they are playing the "architecture of the future" card and wants us to wait for full benefits of Bulldozer's architecture. That's not fair to AMD fans and users. A launched product should offer its end user everything it can, here and now, not in a year from now, when the whole world could end even before that. A future proof architecture should be of concern only to the company and it's management, and while they can be somewhat pleased with Bulldozer, desktop users cannot.
