GeForce GTX 590 Picture and final specfications
 

GeForce GTX 590 will hide two GF110 GPUs under its huge coolers that beside from the lower clocks will be identical to GeForce GTX 580. This means 1024 CUDA cores with 512 CUDA cores per GPU. Dual 384-bit memory buses and 3GB GDDR5 memory.

We have received good indications for how the card may perform, but with slightly higher frequencies and optimized drivers it could become a tough battle between it and AMD Radeon HD 6990.
