The AMD Radeon R9 295X is a $1500 graphics card that's comprised of dual Hawaii R9 GPUs, 8GB of video memory, and uses an Asetek closed-loop liquid cooling solution. The graphics card is capable of 11.5 TFLOPS and boasts 5632 stream processors between the two GPUs.
It's a beauty for sure, at least from the hardware perspective. However, for Linux users, it's likely a bad buy. A single Radeon R9 290 is performing poorly under Linux with the Catalyst driver (and users have also reported some poor results with R9 290X hardware too). The R9 295X is made even a worse purchase under Linux considering that CrossFire really isn't useful under Linux at this time by most of the games out there for exploiting the full potential of the dual high-end GPUs. Of course, if you're thinking about open-source Linux GPU drivers, there is no CrossFire support and its GPGPU/OpenCL support is still in its early stages.
