I'd get a different PSU and avoid the Corsair CX, CS, VS and RM units. I'd also opt for the FX-6350 over the 6300 if you can swing a few more bucks into the budget.
Honestly, it's going to depend on the title. Some titles you can probably game Ultra with that configuration no sweat. Other titles, especially those that are extremely CPU intensive are probably going to require a lowering of settings somewhat. Consider that Witcher 3 basically takes a 4690k and Titan X down to somewhere around 50-60 FPS with everything on at 1080P and you'll understand that the demands of current and future games are rising to the point where yesterdays hardware, of which the FX-6300 that's about three years old is definitely qualified as, is going to cut it less and less as time goes on.
Much depends on the demands of the game, some will clearly be much less demanding than others, and what you've enabled in game. Do you plan to overclock the processor or graphics card at some point?
