Notebook choice

Most systems now support a minimum of 16 G of RAM with two memory modules.  The exceptions are the very slim and light ultrabooks - in these, the RAM is usually soldered in and not upgradeable.

You're probably better off looking at XPS or Latitude minimum - or Precision workstation if the budget will stretch that far.  Once you hit the Precision line, there models that will support four memory sockets -- essentially none of the Inspiron, XPS, or Latitude models will support more than two modules.

Most Intel CPUs at the i5 or i7 level support virtualization - however, they may not support all possible virtualization modes, so buy carefully.  Once you buy a new system, in over 95% of models, the CPU is no longer upgradeable later on.

Hello

Personally, I would go with a Precision M6800 that has a 17.3 " Display:

You can "customize" it to meet your needs.

Go to dell .com and enter in the search box: Precision M6800.

There are always pre-built versions. You want to pick the system that states "Customize and buy."

From there you are off and running to add/change several options, multiple SSD's, huge memory, excellent graphics cards, etcetera.

However, you will spend upwards of $7,000 but you will have Dell's best laptop that will last a very long time so the price of the system is cost efficient.

Moreover, there is a separate division of Tech Support that is dedicated to the Precision Laptop and Precision Workstations. They do not support any other models.

Highly recommended is to choose 5 year Pro Support with NBD onsite service.

For some reason there is no "Complete Care" selection which is vital so you may want to call Dell and inquire. Moreover, you can ask if the M6800 will support virtualization.

In closing, "you get what you pay for."

One of the problem is with the Latitude 14 inch because in a lot of shops here in Germany in the description I could see only 1 available socket. And I already saw in web that some people with Inspiron for example had a problem with virtual software and from my experience a CPU is not enough if your MB doesn't support virtual modes.

I agree with you "you get what you pay for" but for 7 000 USD I will get small home server T series with 32 GB RAM, Xeon and I will run esxi on it + 2 27inch Monitors + Latitude notebook :) I know Precision series but I think they are more suitable for developers and using heavy applications also from my pov they are a little too big for a notebook.

These have two memory sockets but are hybrid systems - they're designed for small business and are effectively the old Vostro  series --- Inspirons with different color schemes.

They're not designed for what you want to do. 

hi,

so as I understand it is better to buy a Inspiron 15 instead of Latitude 14, right?

Not at all - since this application likely has a business purpose, I'd suggest the E5450 or E5550.  The level of build and support is well beyond any of the consumer-grade models (Inspiron, XPS, etc.).
