Help for a laptop build

Nope, same with laptops. Intel Core2Duos are the current best. AMD's Turions are the equivalent of Intel's older Core Duo. You have any online hardware sites in Europe that I can look at for you and find a good deal off of? Otherwise, Dell is a good choice and HP if they sell in Europe. Asus is another good choice. Something a little less mainstream would be Rock Computers, they are in the UK so I'm not sure if that's an option for you. Rock uses Clevo units like the one in my sig which are pretty solid performance units.

Ok, I don't understand the language (Spanish I think), but I can make out enough to help you. I think something like this would be good for you: http://www.optize.es/servlet/ASUS_ [...] ptize.html. Asus is a good brand, it has a strong CPU, 2gb of RAM, a large hard drive and a dedicated card that should be good for your CAD apps.

I was able to build you a similar system off of Dell's website (Inspiron 1520) for around 919 Euroes. Worth the extra money? Maybe, depends on how much brand matters to you.

If you want to keep looking, look for systems with specifications along the lines of the Asus I linked to above. It should give you a general idea of what you'll need.
