Between mini-PCs, laptops and handhelds, there are tons of sub-desktop PCs with gaming-capable CPUs which rely on integrated GPUs to push polygons. Wouldn't it be neat to bolt on a discrete GPU and unlock higher settings, higher resolutions and higher frame rates, on a lovely high-refresh monitor? Maybe even chuck a nice ray-traced cherry on top?
If only it were that simple. Sadly, external GPUs are still something of a dark art.
