We use Dell's Precision 15 5000 laptops. We get them with a Xeon E3-1505M and Quadro M1000M, which performs great in what we're doing (simulation, extremely multithreaded sensor processing, etc.). They're not cheap, but if you want "the best", I'd say they're a good candidate.

I was extremely excited reading your comment, given the prospect of a Xeon laptop.

According to dell.com, it seems there is no option for ECC ram on this device.

The sadness continues...

Agreed, lack of ECC support is the thing that makes this laptop almost perfect. Otherwise, it's fantastic.
