vmware - processor comparison

In the process of chossing a motherbaord and processor for VMware..
dont have a very large budget, and don't mind if it is using a desktop motherbaord....
Given this:
need some stats to help make a decision for a processor for VMWare
have been considering core 2 duo, core 2 quad, i5, i5, phenom
what is the best bang for your buck / cheapest one to use
whats the lowest speced VM ware box that you've setup and how does it perform?
are there any articles online which compare VM ware peformance amongst processors.
how is VM peformance measured / quantified?

is this just for testing? or for production use?

Have a look at this.

You'll also want to make sure the processor support VT so you can run 64 bit vm's

Intel i5 is really value for money, more performance if compared to core2 quad core

Intel Atom N280, performance sux badly :)

No idea, just get the best CPU you can afford

how is VM peformance measured / quantified?
Performance not only depends on cpu power, you need enuf physical ram(avoid disk swapping/dont over commit ram), how you store the VMs(dedicated storage/LUN via FC, NAS, iscsi),  network speed & ofcoz the load itself

"...  have been considering core 2 duo, core 2 quad, i5, i5, phenom "   ==>  Any of these will work fine, but for performance I'd go with a core-architecture Intel CPU.    Which one depends on how you plan to use VMWare (see later comments).    But you DO want to be sure you choose a CPU with hardware virtualization support (VT).

"... what is the best bang for your buck / cheapest one to use "   ==>  This very much depends on how you'll be using VMWare.    If you'll only be running one or two VMs at a time, a Core 2 Duo will have excellent performance.    If you plan to run multiple VMs simultaneously you'll want a quad core ... and the top performing quad cores are the Core i7 series (best bang), but "for your buck" tends to favor less expensive CPU's  -->  a Q8400 would be an excellent choice (only $159.99 at Newegg), as it will work nicely with relatively inexpensive motherboards [This is excellent:  http://www.newegg.com/Product/Product.aspx?Item=N82E16813128372 ];   but a Core i5 750 would have slightly better performance (~ 15% better) for a couple hundred more dollars (mostly for the more-expensive motherboard it requires).      

... You didn't specifically ask about memory, but a VERY important aspect of the machine you build is that it have enough memory to allocate the RAM you specify for your VM's without generating excessive page faults -- that will DRAMATICALLY slow down performance.     If you plan to run multiple VMs simultaneously use an x64 OS and install plenty of RAM.     Another key performance factor is to be sure different VMs are using different spindles for their virtual disks ==> this will eliminate disk thrashing by the hypervisor.    [This is analogous to the performance impact of copying files between two partitions on the same disk vs. copying files between two physically different disks.]

"... whats the lowest speced VM ware box that you've setup and how does it perform? "   ==>  I've "played" with VMWare on a variety of systems, but the lowest spec system I actually use it on is an E6850 Core 2 Duo.    It runs GREAT on this system -- the VM's boot times are competitive with a "real" system (all under a minute).   Here's my VMWare menu for that system:
