Re: 4 CPU's - That's a lot!
"In say trading environments Excel often needs to do significant number and data crunching..."
The moment you try to do that with Excel, you're using the wrong tool.
That doesn't stop people doing it, but i've seen large enterprises using Excel for their accounting system and not noticing $50million discrepencies as a result.
Excuse for not using a proper accounting system? "It costs too much and our developers have been working on this for years"
