Noise, Overclocking, 2D Quality
Noise level of the original GeForce 7800 GTX graphics card cannot be typically heard when a computer case is closed, so, there is no strong demand for even quieter cooling solution when it comes to the model 7800 GTX. Nevertheless, the NV Silencer 5 (revision 3) proves to be virtually noiseless: even in an open test system it proves itself to be absolutely noiseless.
Overclocking potential of the ASUS Extreme N7800GTX TOP/2DHTV did not really impress us: we could not push the speed any further. But that is certainly not a disappointment: the card already works at its maximum speed and, in fact, 1350MHz is already an extraordinary result for 1.6ns GDDR3 memory.
We have also measured power consumption of ASUS Extreme N7800GTX TOP/2DHTV graphics card. It did not exceed the reference design GeForce 7800 GTX substantially: the ASUS board consumes 81.8W, whereas the reference card consumes 80.3W.
Needless to say that the premium graphics card demonstrated amazing 2D quality on our Dell P1110 and Dell P1130 monitors: in all resolutions, including 1800x1440@75Hz, ASUS’ top-of-the-line offering produced a crystal-sharp image without any ghosting or blur.
