Professionals should be aiming at 16GB to get smooth and uninterrupted experience. The all in one computer are not mostly recommended for professional gaming geeks, but if your system is equipped with a dedicated graphics card it obviously is a plus.

Resolutions defines how closely the pixels are packed with each other which decide the display quality. It’s no obvious that a screen with closely packed greater number of pixels would radiate classy content with accurate colors and enough details. For best all in one pc’s, an FHD (Full high definition) resolutions for 20 to 24 inches AIO computers are considered as the minimum and similarly for above 24 Inches QHD resolutions (2560×1440). Surely, professional content creators and gaming geeks would be eyeing to get 4K resolutions or if possible then 5K.


Having your system equipped with latest and useful number of input/output ports will offer you room for creativity by connecting necessary peripherals. Look for a best all in one computer that has a variety of ports, including USB Type-C Thunderbolt 3 port, USB-C 3.0, audio combo jack, and SD card reader, etc.
