Also, 64-bit apps tend to be a little larger then their 32-bit versions (fatter pointers, integers, etc.). With 1 gig memory will be a wee bit tighter (modern 64-bit machines would normally have lots more RAM...). With what is obvious and 'older' 64-bit system, being limited to 4gig of RAM (which is still just within 32-bit address space), going 64-bit with this system would not buy you much. If you want a consistent operating environment, especially if you don't want to maintain two separate sets of updates, keeping all of your boxes at 32-bit for the time being probably makes sense. If and when you upgrade things, going 64-bit might make sense. > > Scot P.
