If you're feeling that your PC gaming rig could use a boost, look no further: Asus
has just announced the GeForce GTX Titan Z dual-GPU graphics card, powered by the best that NVIDIA
can crank out at the moment. It's a high-performance beast, stacked with 12GB of GDDR5 memory and NVIDIA's GPU Boost 2.0 technology. Atop the usual trimmings, there's GPU Tweal: that's an Asus exclusive that "allows users to tune graphics parameters in real-time." You'll be able to modify the clock speeds and voltage levels, along with cooling fan speeds.
All told, you're looking at two NVIDIA GeForce GPUs (876MHz boost clock), 12GB of onboard memory, a total of 5,760 CUDA cores, and plenty of oomph to handle output to a growing stable of 4K monitors. It'll ship worldwide starting this week, but pricing has yet to be revealed. Rest assured, it won't come cheaply.
