Pros
Pro Razer Ouroboros included in the package
The package of the Devil 13 card is quite extensive and Polorcolor adds a lot of stickers, but a wireless Razer Ouroboros mouse is also included - a gaming mouse that generally retails for $120.
Pro A lot of performance for a single card
The Devil 13 uses two Raden R9 390 chips, which allows for a lot of performance on a single graphics card. For example, playing GTA V on a Devil 13 in 4K resolution with maximum graphics settings will result in an average framerate of 52.1 FPS - compared to 57.3 FPS of two seperate R9 390X cards in Crossfire.
Cons
Con Uses previous generation GPU's
The Devil 13 R9 390 has been released a while ago and still uses AMD's previous generation R9 390 GPU's. In june 2016, NVIDIA has released their new generation of high-end graphics cards in the GTX 10XX range. AMD is also working on higher-end cards based on their Polaris architecture. Both new generations offer increased performance, significantly lower energy consumption and additional features such as better support for DX12 games.
Con Loud noise production
Although there are no statistics available regarding noise production of the R9 R390, tests indicate that the noise produced by the cooler can definitely be experienced as annoying. During full load, fan speed averages at 66%.
Con Massive power consumption
The graphics card requires a whopping four 8-pin PCIe-connectors, with a maximum total power usage of 600 watts. Compared to the latest high-end NVIDIA GPU - the GTX 1080 - that's four times as much.
