Introduction
AMD's Radeon R9 280X has been on the market since October last year, but it wasn't really a new product even back then. The card is basically a rebranded HD 7970 GHz Edition with a slightly lower GPU clock, which essentially makes the it a 2 1/2 year old product. Nevertheless, the card still satisfies when it comes to driving 1080p displays at maximum details in all the latest games.
Based on the 28 nm "Tahiti" silicon, the Radeon R9 280X features 2,048 stream processors based on the Graphics CoreNext architecture, 128 texture memory units (TMUs), 32 raster operations units (ROPs), and a 384-bit wide GDDR5 memory interface holding 3 GB. AMD's reference clock speeds for the chip are 1000 MHz on the core and 1500 MHz (6.00 GT/s effective) on memory, which results in 288 GB/s of memory bandwidth.
Today, we are reviewing the MSI R9 280X Gaming 6 GB, which doubles the memory from 3 GB to 6 GB, promising improved performance at higher resolutions. The card is also overclocked out of the box and comes with MSI's signature TwinFrozr cooling solution. Right now, the MSI R9 280X Gaming 6 GB is available for $400 online, a quite significant price premium over standard 3 GB variants.

The Card
At first glance, the card looks very similar to the MSI R9 280X Gaming 3 GB, but only the cooler assembly is unchanged. Everything else, like its PCB design and cooling for secondary components, has been updated. Dimensions of the card are 30 cm x 13 cm.
Installation requires two slots in your system.
Display connectivity options include one DVI port, one HDMI port, and two mini-DisplayPorts. You may use all outputs at the same time, so triple-monitor surround gaming is possible with one card.
The GPU also includes an HDMI sound device. It is HDMI 1.4a compatible, which includes HD audio and Blu-ray 3D movies support.
Two available CrossFire connectors allow you to combine up to four R9 280X cards in a CrossFire configuration.
