The Radeon R9 390 is a higher-end graphics card by AMD with 8 gigabytes of video memory and connections for DVI, HDMI and three times DisplayPort.
Pro Lots of video memory
The R9 390 has 8 gigabytes of video memory. Lots of video RAM isn't particularly useful in most current games, but future titles will most likely take advantage of larger amounts of video memory.
Pro Great performance for 1440p gaming
The R9 390 can handle gaming in Full HD (1080p) resolution extremely well, even with all settings maxed out. Performance in 1440p is also great, averaging 76 FPS in Battlefield 4 with Ultra settings. In Metro Last Light and Very High settings, the R9 390 reaches an average framerate of 53 FPS.
Con High power usage
The R9 390 isn't known for its efficiency when it comes to power consumption. For comparison: during full load, a test system with a R9 390 equipped draws 337 watts of power. The same test system running a GTX 970 - which can be considered as the 390's main competitor - only draws 265 watts.
Con Previous generation chip
The R9 390 chip has been around for a while, and both NVIDIA and AMD are introducing new mid-range and high-end graphics cards in the remainder of 2016, such as the GTX 1070 by NVIDIA and the RX 480 by AMD. Lower priced cards are expected to launch as well, which would render the R9 390 outdated.
