I am looking to buy a new workstation to run a custom app that is heavily cpu intensive. Right now it runs on a Windows 7 (64bit) dual processor (intel 5690) workstation with 192 gb of ram. So, the system as configured has 12 physical and 24 logical cores, yet takes over 30 minutes to do the crunching required. I can see, using Resource Monitor, that the bottleneck is the cpu, not the I/O.
So I want to buy a system with 4 Intel e5 processors (not yet sure whether the e5-26xx or the e5-46xx cpu's would be the better choice).
So my question is: I have read that Windows 7 only supports 192 gb of ram, but does it support 4 processors? When I find a company selling quad cpu workstations, they only offer Windows Server or Linux variants as the OS choices, leading me to believe that perhaps Windows 7 does not support more than 2 processors. Is this true?
