With the Nvidia Optimus driver you get compression and upto 70% of the performance of a full 16x PCIE slot.
Nvidia are currently developing (and probably ATI too, though not confirmed) external GPU for thunderbolt port which is electrically equivalent of a PCIE 2.0 x4. These will come out on next gen PC's and laptops. Sony have already released their version for their laptops.

I can tell you from my test that a GTX 580 on a PCI-E 1x slot has lots of stutters and low fps in Clod with medium to low settings @1920x1080. Arma2 on the other hand, worked perfectly.
