Hi there. I need to choose between one of the following CPU setups.

1 X Intel Core 2 Quad Extreme QX9770

or

2 X Intel Xeon E5450

I need to process a lot of mathematical formulas in as quick time as possible.

The way the formulas are processed is via a VB macro in an Excel 2003 spreadsheet.

I have tested my program on an Intel Q6600 P35 chipset and it completed 27,284 calculations in 63 seconds. Because of the way this program was written, i am pretty sure it doesnt utilize the full potential of multi core cpu's, as the Q6600 was only 4 secs quicker than a p4 Extreme 3.6Ghz CPU

Money is not really an option on this but i need help as to determine which CPU setup would be better.
