Guys remember that the PD CPU being tested is the lowest tier 8 core. There are actually 2 more steps above this CPU. So compare to a 2500k at most IMO. If they manage to fix the power consumption problem while gaining an overall 10% in singlethreaded performance, I think it will be good, especially for upcoming Windows 8.
If they can do that, it won't be a bad chip at all. Now Windows 8.... It's going to be a monumental task to prevent it from going over like Unity and Gnome Shell 3. Looks like the iPhone generation of GUI developers is upon us for the desktop (Lord help us).
