AMD doesn't want to let NVIDIA take all of the limelight with their recent Titan-Z launch so they've gone ahead and rushed out the Radeon R9 295X2 graphics card. This is basically a single-PCB card that houses a pair of Radeon 290X cards in Crossfire. The "good" news is that this combo is available for a mere $1,500 - half price of the competitions Titan-Z.
What makes the AMD Radeon R9 295X2 somewhat sui generis in the world of GPUs is the use of an Asetek closed-loop water cooling system with 120mm radiator and fan for its cooling configuration. There are integrated pumps that sit atop each GPU using micro channel cold plates. The tubes are sealed and heat is exchanged to the 120mm radiator with fan. No assembly is required and it is maintenance free like most AIO CPU coolers you are likely familiar with.
