I have decided to buy a good laptop with minimum of 16GB RAM and 320GB HDD.

I request which will be best suited for the purpose defined below.


Budget cannot exceed $400 ( which is Rs.26000)

Purpose:

* Will be running VMWARE Lab environment with mutiples VM s -minimum of 7-10 VMs, Vsphere etc
* Will be running Cisco UCS simulator.
* GNS3 software ( not simultaneously though)
[For those who do not know GNS3 - it is a simulator for Cisco Routers used for doing practice labs for Cisco Networking Examination at Expert level. It gobbles cpu cycles afaik.]
* apart from this it will be used for watching movies occasionaly and MS office, Excel and browsing net, downloading stuff.

Choices:
Note that all the options are sparingly used/ refurbished laptops in excellent working condition.
Also I have Samsung Evo 250GB SSD and will install in them and install the 1TB that comes along with this laptop in the DVD drive bay by removing DVD drive.

1.
Lenovo T420 with Intel® Core™ i7 processor i7-2620M with dual-core

2.
Lenovo T420 with Intel® Core™ i5 processor i5-2520M with dual-core

3.
HP EliteBook 8440p with Intel Core i7-720QM Processor (1.60-GHz, 6MB L3 cache)* Up to 2.8 GHz with Intel Turbo Boost Technology

HP EliteBook 8440p Intel Core i7-620M Processor (2.66-GHz, 4MB L3 cache)* Up to 3.33 GHz with Intel Turbo Boost Technology

4. Dell Business class laptop with i5 3rd Gen processor.

Question:

a. Of the above options which will best suited to my need provided all these will have 1TB HDD and 16GB RAM and price approximately in my expected range ?

b. Are 3rd Gen I5 s better than 2nd Gen i7s and so should I go for the 3rd Gen i5 ?
 
Solution
Gen 3 was only a marginal update so gen 3 i5 is only a few percent better, thus an gen 2 i7 is going to be better then a gen 3 i5.

For things like VMs or video rendering where you want every core/thread available the 2nd gen i7 is still better then the newest i5.
