My issue is the 32-bit 4GB system address space limitation, which actually will limit you to 3GB of usable CPU memory (even if you have 4x1GB memory cards) if you start using the new 1GB Nvidia cards (that will be mapped into device address space). Of course you can start paging the scenegraph, but I also have a handful of data caches that can grow pretty big under some conditions, so a larger 64-bit address space should at a minimum immediately get me access to the full 4GB of physical CPU memory for starters. Or maybe my 64-bit expectations are too high? Bob. -- Robert E. Balfour, Ph.D. Exec.
