Beware of laptops with switchable graphics. My Sony Z is awesome...
EXCEPT for the fact that the switchable graphics mechanism makes it
impossible to update the NVidia drivers (without either hacking
together a custom driver package or hacking the bios to force the
machine to use only the NVidia graphics). I'm beginning to wonder if
Sony will ever update the graphics drivers for my machine. (very
irritating to have Sony blathering on about supporting CUDA... and
then failing to support CUDA).

Laptops I'd consider if I had to do it all over again (by order of

Lenovo w510
Dell Precision Mobile Workstations (4500 and 6500)
Lenovo T410 (uses Optimus -- software switching between internal and
NVidia graphics. Confirm driver upgradability before you leap!)

As for the quad vs dual-core... i7's do come in dual-core as well as
quad-core. You'll probably want to go with a dual-core i7 if you're
going with a laptop, so worry less about CPU and more about screen
quality, video card, memory and hard-drive. IMO, solid state drives
are a must---but you should probably upgrade the drive yourself as
Lenovo and Dell were waaaay overcharging for these components. The
Intel x25-M is a good choice (although appears to be currently phasing
out due to Intel releasing it's new 510 series).
