The testing by HardwareCanucks revealed that Radeon R9 280X was CrossFire compatible with the Radeon HD 7970. This has surely brought some good news for the users of HD 7970. The users who were previously hoping to include a Tahiti to the CrossFire can satisfy their wish by the Radeon R9 280X addition which is comparatively cheaper than the HD 7970 models available online.
Most of us would love just one 4K monitor for our gaming setup, but the guys over at the Windows Lab have opted for three! The math is easy three 4K monitors gives you a 12K display!

These guys has to build a custom driver to make this all possible, but it is very impressive!
