Well, it was hard to believe this, but I check it and I agree.
The modding part can still work. This is how you do it:
1. Put the card into your computer.
2. Open the device manger and check the properties of your card. Look up its hardware id, which can be found on the details tab (select hardware ids), and looks like "PCI\VEN_*&DEV_*.......".
3. Download the latest cartalyst legacy for HD 4k cards which is made for your OS.
4. Look up the .inf file in the extracted package and open it with notepad.
5. Find the section where it lists cards with their hardware ids.
6. Find a random 4650 and replace the device id to the id of your card.
7. Save the file and try installing the drivers again. (Note: The digital signature will be gone, you'll get a prompt when attempting to install.)
Note: If the install manager doesn't want to install it, try installing manually through the device manager.
