Regarding Spot collector hardware needs, I think they relate to the motherboard hardware and not to the graphics card unless the graphics card uses motherboard resources and then a limitation in resources could affect the graphics system and display capabilities (probably on low end systems) when under heavy loads.
+ Neither SpotCollector nor any other DXLab application directly utilize graphics card resources. They rely on Windows to display their windows using whatever hardware is provided for that purpose.
