Size, noise and heat generation
Very short at 18.5 cm, the 5750 does nevertheless come with a double decker cooler. Apparently however, the cooling system we saw on our test card isn’t the same on all the models on the market.
The fan was quite noisy. In idle, while the chip was maintained at 38°C, noise levels were 42.4 dB(A). This is already noticeable and you certainly couldn’t call it quiet. We would have preferred a slightly warmer card with a quieter fan.
In load the chip doesn’t get any hotter than 82°C for noise levels at 48.4 db(A). Although a little noisy, this is more or less acceptable and will generally be tolerated by those in the same room.
As with the whole Radeon HD 5000 series, energy consumption is nicely contained. At idle we got 80 W for the whole of our configuration. This is an excellent score! In intensive 3D usage we took a reading of only 190 W, again very good. An eco friendly card! Power comes via a single PCI-E 6 pin connector.
Overall we don’t advise this card for those who have high res screens. It's more aimed at those with low definition – 1280x1024 for example. Even then, you need to make compromises in terms of your graphics settings on heavy games. If this doesn’t worry you too much or if you don’t do a great deal of gaming, this model will do you fine. Otherwise, go for something a bit more powerful.

Taking the example of World in Conflict, where the 5750 obtained 33 fps at 1280 with filters activated, the 5770 was up to 39 fps. In Far Cry 2, at 1680 but without filters the respective averages were 51 fps and 61 fps.
