shouldn't you avoid pairing intel processors with AMD cards in laptops? Just a question because I'm also looking for a gaming laptop with some portability
Not necessarily. AMD and Nvidia mobile GPU's are usually built around the MXM standard connector. So in that case they are actually somewhat similar when it comes to mobile GPU's for low-med-high end. AMD's mobile gpu's may actually be slightly weaker (at the very high end), but are actually a bit more efficient power-wise (at similar mobile gpu levels).
What's more important is the cooling systems in the laptops. For example - my gaming laptop has a 5870M, but it gets way too hot if I max out settings in certain games and auto shut downs. I've found out my GPU actually has nearly 0 coolering besides the core, and the internal fans "cooling" it.
Out of the 2 WR2 listed, I would go for the second choice, better GPU, higher resolution, and better CPU, and its only about 150$ difference.
