We were pleased to see that the 850 has on-board Intel Gigabit LAN with automatic installation of the Intel I211-AT driver and no need for separate driver installation. The software allows the onboard LAN port to work at full 100/100Mb for FTP and SMB. You also get system LEDs which light up when new software is being installed.
We are not impressed by the work put into making changes to ASUS's AURA RGB software. The menu system in the old menu does not feature the new settings and the RGB modes aren’t available to choose from. ASUS has added a synchronise all setting that applies the pre-configured RGB settings and a special gamer mode but while it’ll make it easier to use a single controller for a range of settings this seems like overkill when you could just disable on-board RGB.
The ROG GameFirst IV software is now at version IV and is the ASUS packet prioritisation software of choice for the on-board Intel I211-AT Gigabit LAN and Realtek 8822BE WiFi. There are a variety of application profiles that can be set on a per-application basis, nominating one application as higher priority over another will allow it to use more of the total available bandwidth and have higher priority for send and receive requests.
The most noticeable thing about the T.sonic 840 player on the front side is its 1.8-inch color LCD screen with 176 x 220 resolution. This nice screen sits just above a three-phase wheel for control of on-screen menu choices and music selection. It connects to a host computer through USB 2.0, also being able to serve as a flash drive for storage of non-media files.
