Sorry I don't understand French so I just am guessing that you need HD 5900 Series GPU card drivers?
All HD 5xxx GPU cards are not supported by AMD with driver updates. You have choice of two last AMD Drivers:
1- WHQL 2015
2-BETA 2016
The only HD5900 Series GPU card shown in AMD Download page is the HD5970 GPU card. You can download the last 2 drivers from here: https://www.amd.com/en/support/graphics/amd-radeon-hd/ati-radeon-hd-5000-series/ati-radeon-hd-5970
If this isn't what you need then you need to translate your post into English, Thanks in advance.
