A 32-bit application can not go above 3GB in best case, often much less due to dynamic linking, threads etc eating significant parts of the address space. 2.5 GB or even less is more realistic to expect. Well, there is also some experimental 32-bit OS:es getting close to the theoretical 4GB limit per process (2^32 == 4GB), but only at significant performance penalty and added internal complexity. A 64-bit application (which also requires 64-bit CPU and 64-bit OS to run) on the other hand is practically unlimited in size, only limited by how much memory you can stuff into the box.
