The GeForce GTX 770 WindForce 3X Specs

 GIGABYTE  company announced a variant of its GeForce GTX 770 WindForce 3X graphics card with a factory-overclock, and 4 GB of on board memory. Pictured below, the card combines a non-reference design PCB designed in-house by GIGABYTE, with its new Wind Force 3X cooler, which can handle thermal loads of up to 450 W.

• The New WindForce 3X ard ships with clock speeds of 1137 MHz core,1189 MHz GPU Boost, and 7010 MHz memory.
• Against NVIDIA-reference speeds of 1046 MHz core 1085 MHz GPU Boost, and 7010 MHz memory.  The card features 4 GB of GDDR5 memory across a 256-bit wide memory interface, which at its given speed, churns out a respectable 224 GB/s of memory bandwidth. 
• The memory in WindForce 3X is spread across sixteen 2 Gbit memory chips, eight located on the reverse side of the PCB, without a back-plate.
•  The new WindForce 3X cooler uses two aluminum fin stacks to draw heat from the GPU, using six copper heat pipes; which are then ventilated by three 80 mm fans.
•  The cooler works  to keep GPU temperatures under 80°C, letting it sustain GPU Boost clocks. GIGABYTE should price the WindForce 3X  card at $499.99. A lucky few may have bagged it on Newegg for $449.
