Selecting computer for windows 2008 server to run IIS

I have a VMWARE virtual appliance (windows 2008 server with IIS) running on Intel quard core processor with 6GB Ram

but its running slow for heavy multithreaded ASP .Net services

I am trying to move the vmware image to faster computer

If i can get some advice on selecting a better computer, that will be great help for me

My budget is less than $1,500

I am interest in this desktop computer, so I can use it for my every day home office work and run server using vmware workstation in background

Thanks for any help i can get on this

You would probably be wanting to look at workstations that have dual CPUs. I do not mean cores but actual dual CPUs.

thanks for the advice logic_earth, so far I was unable to find workstation with dual CPUs for around $1,500
