This Radeon HD 7790 '13Series from Club3D has definitely been able to convince us. Of course it's not the fastest HD 7790 on the market but I think it's one of the most interesting. First of all it's noiseless in idle and also while gaming. We were really surprised to see this tiny cooler hold well against FurMark with the fan at 30 % and stay quiet dead when gaming BattleField 3. Second it's the cheapest HD 7790 around and one is going to choose an HD 7790 because of a limited budget so this makes sense. Last but not least with AMD's Never Settle Reloaded you get BioShock Infinite for free with the purchase of this card.

Performance of this product in particular has nothing special, the additional 30 MHz on the core gives only 1.5 % additional performance on average. But the HD 7790 in general benefits of the best Performance/Watt ratio and a good Performance/Price ratio.
You won't be able to play games with highest graphics settings with this card mostly due to the 1'024 MB of memory but the card is powerful enough to play even recent demanding games at 1680 x 1050 with high settings and 2xMSAA smoothly.
The power consumption in idle is really good. Our entire setup wasn't drawing more than 51 Watts, which is remarkable. Under load we measured only 105 Watts which is very good considering the performance you get.
