I have enough money to buy the Mac Pro, but I meant that it is more expensive than the Mac I am building, which has higher specs.
If you buy a secondhand 'classic' Mac Pro preferably a 2010 model then you can upgrade various items in it to build a very capable Mac almost as fast as the 'new' Mac Pro.
You can fit an SSD drive - preferably a PCIe card type in a PCIe card adapter, you can fit a newer much more powerful video card, you can even upgrade the CPU chips to a certain extent and you can fit up to 128GB of RAM although that much is overkill for most people. It will of course run the very latest OS X 10.11 i.e. El Capitan.
As such it will be more than capable of running Xcode and FinalCut Pro X.
If you will only be using Final Cut Pro X and not Adobe equivalents e.g. After Effects and Premier then an AMD card is the best choice, if your going to be mainly using Adobe software than an Nvidia card is the better choice. In fact as the classic Mac Pro can use an Nvidia card unlike the new Mac Pro it could even end up being better than a new Mac Pro for Adobe software use.
Depending on how mad you go with upgrades a secondhand classic Mac Pro even with upgrades would likely cost no more than a Hackintosh and certainly less than a new Mac Pro. It would of course be perfectly legal to run OS X on it and even Windows 10.
The classic Mac Pro can run a 4K monitor if you get a suitable AMD or Nvidia video card. If you get an Nvidia GTX 970 or GTX 980 it can even run a 5K monitor!
