For longer streaming, we recommend to use a desktop instead of a Laptop.
Performance is the main factor in choosing a laptop or a desktop for longer streaming. A desktop is better suited for long hours of performance and lots of multitasking.
In a desktop, a CPU creates quite a bit of heat as it operates, so it requires a bare minimum of a cooling fan and a heat sink; the sink is composed of various plates and channels that work together to constantly draw heat away out of the CPU and away from the processor to prevent meltdown. Because of the heat issue, laptops have CPUs that run with a lower speed and voltage. In this manner, heat is reduced and less power is consumed; the trade-off is a processor that operates at a slower speed.
The main difference between the two computer types is found in the way such components are put together. Laptops, because of their small size and portability, obviously need more compact components. Desktop computers have everything housed in a (usually) large CPU tower: a motherboard, a hard drive or two, audio/video cards and other necessary hardware elements gathered together. Components like the keyboard and mouse connect to the computer itself via wires or infrared wireless technology. Most CPU towers have a lot of extra space for more cards, cables and cooling fans.
There’s usually only a single cooling fan, since there isn’t much space for more than that, and space for only a couple of cards. For this reason alone most laptop components have to be both compact and have hardware that produces a lower level of heat.

We found through our testing, that on the desktop, you can add capture cards for better HD streaming quality, while on your laptop you are restricted to use the build-in webcam, an external camera or a capture card that connects to USB ports.
Here you can view a list of the supported capture cards that we have tested and are actually using.
