I'm looking for a 15" laptop with a DX11 GPU. The HP Envy 15 has the ATI 5830. It seems great, but I thought I'd look for more options. This will mainly be fore giving demos on DirectCompute and perhaps OpenCL.
Any other laptops I should consider?
AFAIK, there are still no mobile versions of DX11 GPUs from nVidia. So you do have two choices: to buy laptop with DX11 GPU from ATI/AMD right now, or to wait for mobile DX11 GPU from nVidia.
