I have an HP Envy 15 with an ATI 5830 GPU and a quadcore i7.  The fans are always on even when idling.  Does anyone know of another DX11 15" laptop which might run cooler?  I can still return this one.  My budget is about \$1900.  I need DX11 for purposes other than SW, but I thought I'd ask here since the community is knowledgeable.
