1) 32 vs. 64-bit: If the operating system is before XP or before then they can't handle 64-bit programs. 64-bit is slower for small operations but can use as much memory as available on your system and is not limited to 2GB as its 32-bit counterpart. This is important if you are doing a lot in memory.

2) Excel 2010 can be installed as 32 or 64-bit, prior versions were all 32-bit

3) I prefer Windows 7 to Vista, but don't have any benchmark comparisons to share with you. I have Excel 2010 on running on both XP and 7 and both function the same but since the hardware is different I can't tell you which is faster.

Hope this helps.

thank you very much for this detailed and helpful reply....I am sure you knwo that excel 2003 can be blazingly fast on a simple processor - I wonder if the excel 2010 on multiple processors can easily outperform it???? thank you so much for your help!)
