最后还是用原厂的mac 版680 4G搭配mac pro 3.1 4k@60（hidpi），折腾了一堆的显卡都是有这样那样的问题，准备休息一下，再一张张显卡折腾

UNFLASHED "Windows Only" GPU CAVEATS
When you used OS X 10.8.3 to boot your Mac Pro with GPUs lacking "OS X aware" firmware, there is no Apple logo white startup screen. It goes straight to Finder (or the User Login screen). This isn't a problem until you want switch boot volumes by holding down the Option key during Restart or Power Up. That does not work. However, you can still choose other boot volume(s) in the OS X System Preferences > Startup Disk. If you are running Windows in a Boot Camp volume, you can use the special Boot Camp Control Panel to choose the OS X Startup Disk. You can also reset the PRAM at Restart or Power Up, thereby forcing it to boot with the default OS X volume.
As indicated above, some unflashed GPUs don't run at the full PCIe 2.0 bus speed (e.g. Radeon HD 7970 GHz and GeForce GTX 690.) That may or may not limit performance, depending on what apps and what functions you choose.
看到7970如果没刷好就是不能运行在pcie 2.0
