Even in spite of my age I thought I was well educated when it came to computers though I'm a little in the dark when it comes to 64 bit processors and operating systems. My current photography workstation is an older system with a single core Pentium 4 prescott 3.0Ghz CPU with 3GB of ram and an AGP video bus (what a rude awakening it was to discover that installing 4GB of ram was a waste of time and money due to my computer hardware taking up almost 1GB of the 4GB addressable memory space available in the 32 bit system). I'll be looking to upgrade to an AMD or Intel multiple core system in the future, most likely with a 64 bit operating system so more ram can be utilized. Questions... can 32 bit software run on a 64 bit system or will I be left with some apps that work while others don't? Does it make any sense to stick with a 32 bit OS with a multiple core cpu and limit myself to 4gb of addressable memory? Any advice would be appreciated.
Richard
