If you go with a 7700 non-K (saves $30-50), you don't need a cooler (saves $50-150) and you can go with a B250 or H270 motherboard instead of Z270 (saves $30-50). Overall the 7700 non-K system can be over $200 cheaper, which is enough to move up from a 480 to something like a GTX 1070 - a much faster GPU, which will provide a far better experience in games.
