if i want the future proof cpu what cpu you suggest?i mean more core..

The current market will be heading towards multicore and single threaded performance is no longer relevant to the current standards. This is not to say that single threaded performance is not important, it does definitely contribute to a stronger multithreaded performance but what I mean is that having a single core is no longer feasible. I can imagine that SB with that die size at 32nm but instead of 4 cores they make into a single huge core will not perform as well as the current SB would in majority of tests. There is a diminishing return for more cores and there is also a diminishing return for increased core/architecture complexity.

Like I said before, BD is a server CPU where multithreaded applications are custom made to take full advantage of the hardware but it will definitely not be good for the normal consumers. It still falls short of being a good server CPU though as I think the 16C Interlagos will barely beat or similar to the 12C Magny Cours.

As long as the software is able to make full use of the parallelization, you can have as many cores you want and cluster computing and HPC does just that with thousands of similar cores working in tandem. Most cluster computing will use GPU as a form of parallel compute but the K computer does not have any GPU and relies totally on the CPU power itself but the only reason GPU is being used is that the power required to achieve a higher GFLOPS is much more efficient than using CPU alone. The K computer is at the top currently but it's power consumption is quite bad compared to clusters based on CPU + GPU.

AMD's Bulldozer Beats Own Clock-Speed Record: 8.461GHz

I would say all hope is not lost, at least there is a competitor to Intel
