Bought to replace an Nvidia GTX570 factory overclocked Gainward by. Equivalent performance (barely better on some benchmarks) but very happy with the purchase because the noise of the 570 full load was unbearable (a real vacuum cleaner). On this model, even at full load the card remains perfectly silent. The Asus DirectCU II system works really well. CUDA for use in 3D: Without being exceptional, displays the correct rendering times (on Blender 3D software) compared to its price, however the lack of RAM is quickly felt to load complex scenes. Gaming for use: without any push down, all the recent games really runs very well on it. A good compromise for the budget.
