I have a MacPro Mid 2010, 5,1. with a Radeon HD 5770. I understand that install Mojave the graphics card must be "Metal Capable". Is the 5770 metal capable? If not what should I replace it with?
Mac Pro, macOS High Sierra (10.13.2), 2.8 GHz Quad-Core Intel Xeon
Not compatible. If you search the Mac Pro Discussions, you can find other threads about recommended cards and potential problems.
Before putting money into a new card, give some thought to whether you need Mojave for anything, and whether your software will work with it.
I've decided to go with the upgrade and bought an MSI HD 7950 that's been set up for Mac primarily because I've been wanting to upgrade the card for a while due to the sluggish rendering that I'm getting from my CAD program and will probably wait for the next iteration of Mojave to update the system.
Check here. Any of the listed cards are "Metal Compatible" and should work just fine in a 5,1 under Mojave.
Hope it helps!

Just Curious. I am a developer looking to move to Mohave. I am in the same new graphics card pickle.
@Apple - Why aren't the ATI 5770 HD and ATI 5870 HD APPLE GPUs sold with MacPro 5,1 compatible with METAL?
