This R6850 combines all these qualities:
Factory overclocked, which makes it almost as good as the 6870 model.
Particularly short and also the power supply connector conveniently placed on the side.
Consumption remains reasonable which saved me having to change my diet.
Very silent in normal use and unobtrusive enough in 3D in games.
I advise the use of the application MSI Afterburner, came in the product, which allows to manage finely setting clocks and monitor in real time the status of temperatures and fan. Those who have a Logitech Keyboard Series "G", with integrated mini display, these data will also be displayed directly on the display.
For Afterburner, use, preferably one supplied with the card, the beta version on the MSI website: it is now able to include in its games videos recordings.
Note however that I first received a defective copy which caused me some random PC gels (hence the star less) -probably problems cooling-bad.
But it made me realize once again the quality of customer service Amazon allowed me to enjoy a standard exchange without discussion and by sending me a copy of * replacing * before having to return the defective product.
No more problems with my new card since.
