TechPowerUp rates this card 7/10. It offers high 3D performance and lower noise than the Radeon HD 6990, but it's too expensive and the performance is lower than the Radeon HD 6990. Interestingly, the card also notes that their card blew up during testing because the power limiting system didn't work reliably.

"Today NVIDIA releases their new GeForce GTX 590 flagship which is based on two GTX 580 GPUs working on a single card. AMD released their dual-GPU HD 6990 design just two weeks ago, with power and heat being the decisive limit on performance it will be a tough fight between those cards."
