With the money you have left over, you can spend it on a case with better aesthetics, cable management options etc. I can't find the GPU card clearance for this case, but it doesn't look as if the 770 will fit.
Excellent choice! The layout in this case is perfect for the card, as you can remove the drive cages that you most likely won't be needing to not only create more space for your card but also increase airflow through the case. Plenty of fan options and it certainly looks the part - good luck with your build!
If you don't plan on SLI or Crossfire, then go for it! It's a great price, too! I just say this because the second PCIe 3.0 slot in this board only runs at x4 and is pretty crappy for dual card configs.
