Performance difference between 32-bit and 64-bit OS when i use Visual Studio 2010?

Question

Is there a performance difference between 32-bit and 64-bit operating system when I use Visual Studio 2010 ? (Mostly working with .NET and C#)

Answer 1

don't know all implication, but one major benefits of the 64bits is that the process can go further than 2GB of memory.

When you have dozens of plugins, or large projects with heavy process (Resharper real-time analysis for my experience), this can be a large benefits to go beyond 2GB of ram.

Also, 64bits will allow you to beyond the <4GB limitation of the OS..
