I am wondering which is better for me to use. I am currently using excel 2003. I have several large files with lots of vlookups to other large files and many cells with formulas that need to recalculate based on the vlookups. Currently the files update very slowly. Would they be faster in Excel 2007? I don't use many graphs (I have heard they are very slow).

G'day and welcome to the forum,

Here's a bit of light reading for you.

Hope this helps

Cheers
