Gustafson's law says that while throwing hardware at a problem, increase the problem size of an application as well to improve scalability of hardware. There are many discussions supporting Amdahl's and Gustafson's laws. But, if an application can scale without increasing data access contention, it can benefit from multi-core processors. All applications may not scale their problem size, but there are many applications that can.

3D stacking is probably that technology, which can lead to memory-on-processor designs with pretty much unlimited memory bandwidth.
