Mathcad 15 32 Bit Performance in Windows 7 64 Bit

I am currently running Mathcad 15 on Windows XP SP3 which is a 32 bit operating system.  A Mathcad 15 worksheet I am running has to do a LOT of number crunching.  Mathcad 15.exe  is running my CPU usage at 99% and a RAM usage of about 480,000 kB, as well as locking up once in a while requiring a reboot.  I already broke the worksheet down into a number of smaller worksheets, got rid of  unecessary XY plots, and got a summation of a summation to work the fastest way possible.  Also tried decimation to reduce the load on the system, but found I can't use it, since I lose some of the input data when I do that.

 

My company's MIS department wants to give me a new Windows 7 64 bit machine.  But I notice in the Mathcad 15 specifications that it will only run as a 32 bit application on a 64 bit operating system. 

 

So will running a newer PC with Windows 7 64 bit help me any?

 

Also I notice under system requirements none of the newer CPUs are listed.  With what newer CPUs is Mathcad 15 compatible?
