I am confused b/w Intel Core i7 3612QM & Intel Core i5 3210M.
I'll mostly use the laptop for network testing and penetration, so i would run Windows 2008 server, linux, on Virtual Machines (VMware or virtualbox), and may run 2 or more VM's at same time.
What processor should i select & will it make a huge impact from i5 to i7?
I'll be having 8GB ram.

Both can do the job.

The quad core CPU will probably give you better performance overall if you have a heavy workload on the VMs.

I'm just not sure that can an i5 handle windows server 2008?? As i said, i'll be doing some security tests running simultaneously on host machine, so host machine will also need some processing power?

If i am not wrong, i5 has two physical cores and 4 threads (logical Core), and i have to denote one physical core to the VM, would one core will be enough to run Windows Server 2008?

That's an option, not a requirement.
For what you describe use the default settings and let Windows decide how to use cores and threads.

ok, can you tell me how many vm's can this i5 handle simultaneously??

With 8GB of RAM? 512MB RAM per VM plus 2GB RAM for native OS?
Probably 10-12. But the performance might suffer.

Core i7 laptop could handle the same amount but it should have better performance (4 cores, 8 threads of course).

What's the price difference between the 2 CPUs?

will the VM's stutter under i7?
i5: $225
i7: $378

It's possible they might.
Depending on the number of VMs, the workload of the VMs and workload of the native OS.

Right - there's more to that than just a different CPU choice in the same model.



Am I right in thinking you don't really need to pay for a copy of Win7u Home Premium to do your work?

How about the business class Dell Vostro 3750 notebooks?
Can you get an i7 Sandy Bridge CPU without Win7?

I can easily run 6 Linux VMs on a Windows 7 host operating system on an older i5 laptop with 6 GB of memory. I was using it when I was recently teaching CompTIA Linux+ and Security+classes to demo some of the Linux tools available. Once I got more than 6 guest operating systems using between 512 MB and 1024 MB each the machine started to slow down.

so, i5 is a good deal, but i don't think that it's future proof for next 3-4yrs, as i won't be buying another rig for me in next 4 yrs..

If you feel that way there isn't any question about which option to choose, right?
