I thought I had covered most of the custom GeForce GTX 1080 11Gbps graphics cards coming out, but there have been a few that have slipped through my otherwise strategic GPU detecting radar.
Enter the brand Kuroutoshikou, from Japan - with their upcoming GeForce GTX 1080 8GB 11Gbps OC Gaming graphics card. Kuroutoshikou clocks their custom GTX 1080 8GB 11Gbps card at 1657/1797MHz for base/boost, respectively. The 11GB of GDDR5X is at its stock 11Gbps on the same 256-bit memory bus, resulting in 352.3GB/sec of memory bandwidth.
Kuroutoshikou uses a dual-fan design, requiring a single 8-pin PCIe power connector and 180W TDP.
