Hardocp:"We see no reason to purchase a GeForce GTX 470. It provides no gameplay advantages compared to the competition, and will actually end up costing you more power and dollars for the exact same performance you can get with the Radeon HD 5850. Factor in the power consumption, and it doesn't seem worth it. If you have an HD 5850, stick with it, the GTX 470 is not an upgrade. If you are contemplating a great performing graphics card, for a decent price, the HD 5850 is still the best choice.
The GeForce GTX 480 is more relevant in the market but it hasn't exactly come out of the gate wowing us with performance either. There are some games where it is faster than the Radeon HD 5870, and there are some games where it is even with the Radeon HD 5870. Factor in the cost and power, and include the ability to run Eyefinity on a single GPU, the Radeon HD 5870, to us, seems like the better value for the gamer right now."
