On my K3 the cover art displays on the entire screen and is thus taking up the entire 600 x 800 pixels. Which is a 3:4 ratio.
The DX has 824 x 1200 pixels, so if you want the cover art to be big enough for a DX without stretching, you need to consider that as well. This is appx. a 2.75:4 ratio. I'm not sure why they used a different ration than the K1, K2, and K3.
To be safe you could use a 900 x 1200 pixel cover art. It would rescale perfectly to a 3:4 ratio for the K1, K2, and K3. It would be resized a bit for the DX, but still look okay I think.
If you use a the Amazon DTP to create your Kindle book, good luck. The DTP does weird things with image sizes. (I'm talking about embedded images and not the cover art.) I used to know the size limitations but have long since forgotten. Below a certain size images are automatically doubled in size making them look crappy on the Kindle screen. Above a certain size DTP leaves them alone. It is some weird non-intuitive size, so Google for it or just experiment.
