Windows 2008 server and Core memory utlization

I am about to buy a new server for a windows 2008 AD upgrade.

Does Windows 2008 Server Standard R2 x64 support multithreading? if so, can it utilize a quad core chip or will it be a waste and just go for a dual core?

Windows Server 2008 Standard Edition can support up to four physical processors, regardless of the number of cores on each processor (up to a maximum total of 32 cores on 32-bit and 64 cores on 64-bit). When possible, choose 64-bit processors due to the benefit of additional address space. Research data has shown that two CPUs are not as fast as one CPU that is twice as fast. Because it is not always possible to get a CPU that is twice as fast, doubling the number of CPUs is preferred, but it does not guarantee twice the performance. It is important to match and scale the memory and I/O subsystem with the CPU power and vice versa.

Hi Windl,

So you are recommending two dual core processors instead of a single quad core?

The short answer is, yes - two would be faster in most scenarios, and hyper threading is "standard" ;)
Right...how does that work with VM server 2.0? Im installing the windows 2008 on vmserver 2.0 and It will only support up to 2 processors...is that a limitation of VMserver rather than windows?
