On a slightly related note, I'd like your advice on getting a high-performance laptop also:

My reasons are that because of my job I travel A LOT, so a desktop machine for gaming is out of the question.

Therefore: my budget is about 2000€, and my requirement is that it runs ETW smoothly, and is no bigger than 17' - otherwise it really isn't a laptop anymore.

So there, I'm admitting not to know everything and asking for help. What do you experts suggest?
