While gaming laptops usually contain powerful processors and ample amounts of RAM and storage space, they lack a workstation graphics card - such as one from the Nvidia Quattro line. Such cards are usually better at pumping out the high number of polygons required for 3D work. A high-powered gaming graphics card, such as those featured in most gaming laptops will usually offer decent rendering performance but will lack the extra features and specific driver enhancements and optimizations of a workstation card.

Thanks for the very informative response, Geoff!
No problem, I'm glad I could be of assistance.
