In the video below, you can see the N2830 running in real time Windows 8.1 and some random programs, with multitasking involved. The test was done on an Acer Aspire ES1-series 15.6″ notebook with 4GB RAM and a mechanical 5,400rpm hard drive. Check out 1080p YouTube video playback in Internet Explorer, some basic editing of a 5-megapixel photo in Paint.net application, rich text processing in WordPad, and switching between apps via ALT+TAB key combination. Everything worked pretty much smoothly.
