So, I currently run on my build a Radeon HD 4890 on Windows 7 64. It runs really well, but I've been interested in upgrading to Windows 10. (Even though I love 7's interface) The only problem is, the 4890 is an old card, and when I looked on AMD's website, they did not show a Windows 10 driver for it. I have, however, been told by a few people that the current drivers are still compatible with Windows 10. Does anyone know if I can do this upgrade with my current card? I'm looking to buy a new card next black Friday, but that's a while away. Thanks in advance
