Ok, I need help making a decision then. What's better: a fiio e9 and excellent sound blaster card or fiio e9 and fiio e17 dac? Would they sound the same? What would be different? If I went with an external amp/ dac would I still get simulated surround sound audio like Dolby Headphone?
You are far better off in your situation getting a sound blaster Zx (gaming) or a Fiio E10 (desktop, not gaming).
The E9 is an amp only; outputting from your motherboard to it would be noisy and not worth the cost. You don't need the E9 at all either anyways.
If you get a discreet DAC, you will not be using dolby headphone or surround tech. At all. It will do the processing. Surround tech is emulation and based on software, so it goes hand in hand with a soundcard, not an external DAC. An amp has nothing to do with this.
Based on what you're saying and describing everything points towards a sound card for you. I wouldn't even get the Titanium HD. I would get the SoundBlaster Zx. It has a great setup for gaming, a very good DAC onboard, a great opamp onboard that powers headphones just fine, up to 600ohms no problem, and has an external terminal to plug everything into with a volume knob. If I was to get a soundcard, this would be what I would get, for a cross between gaming and good audio in one package. It's not ultra expensive either.
