If you're getting bored of C++ then it's probably because you're not creating anything that really motivates you. You've probably learned enough C++ to start making simple games, so I suggest picking up an API such as SDL. After becoming somewhat familiar with the basic operations of that API, start making simple games such as Tic-Tac-Toe, Pong, or Snake. Sure, there will be gaps in your knowledge as you create these games, but you can learn as you create. There is no need to learn absolutely every aspect of a programming language or API before you start making games.

All programming languages become boring eventually, because the user confuses their own lack of direction with a fault in the language (not that I'm accusing you of that in these circumstances). Except Brainfuck. I can't see how you'd ever get bored, because you'll never understand what is going on :)

If you're trying to produce a game, using an existing framework / engine will help you get there quicker. But if you're truly passionate then it's inevitable you'll one day take a step back and implement the same things for yourself, so it's where you start.

I've made Tic-Tac-Toe more than 3 times (with and without arrays). I prefer directx to open .

In that case, it's time to move onto something bigger. Try something that takes place in real time, such as Snake or a shoot 'em up. After that, you might try making a simple platformer.

In the console?

No, you'll need to start working with graphics. Select an API and learn some of its basic functions (creating a window, getting user input, drawing graphics, etc.) then start making simple graphical games with that API.
