"he XFX Radeon HD 6790 is a very good video card delivering a very good 15% speed increase over the Powercolor Radeon HD 5770. The XFX Radeon HD 6790 operated at a cool temperature and the Cooler was quiet. Some of the speed increases especially for Hawk 2 for example are impressive and are probably due to the use of the Barts GPU with it's improved Tessellation performance. The XFX Radeon HD 6790 has some good positives such as power consumption, it's quiet, AMD Eyefinity, AMD HD3D and it's very good value for money."
