The MHz war is over, so is IPC war.
Windows 8 will be more threaded, all programs in the future will be more threaded. If u buy a BD now, all your programs in the future will get faster than if you used HT CPU.. ie: If u buy BD now, 3 years from now it's faster running the same program, because that program is now multi-threaded.
IPC only matter in old programs and outdated platforms that are stuck to 2GB memory and 32bit OS. Once a single developer knows the 64bit space and multi-threading, then IPC won't matter in the business world either. Which is what Intel CPU are designed for, business. Not home users.
IPC ONLY matters in Intel business application, namely BAPCo.. How fast of a spread sheet do you need?
The future is quite easy to see & understand, namely a core for every thread running on your system.
As.. no matter what single application, game, or program you want to run, it will reside within an Operating System. But BAPCo & Intel want you to believe otherwise, because it sells chips to ignorant Governments, using BAPCo... & of coarse end-user who jump on the same bandwagon.
Intel will have 6 & 8 core out in 2012. Trying to bash AMD for realizing Win8 before Intel, illustrates a reactionary need within you.
