After reading this guide and The Nameless PC Gaming Audio guide I have come to the conclusion that I do really want to invest in a good gaming headphone and I at least have a decent clue where to start. I have about $300 dollars to spend (350 max) and don't really want to go over. I also don't have a sound card and I don't have room for one either (PCI-E slot blocked by 2nd GPU). I was at first leaning towards external sound cards like Asus Xonar U7 but I think that I can do better for cheaper with a decent DAC/AMP like FiiO E10 and virtual surround sound software (i.e. Razer Synapse 2.0). Im a huge gamer and split time better FPS and MMOs. Ive been stalking this website for about 3 weeks and see that the members are extremely knowledgeable and helpful.
[Edit]: From what I can discern I am leaning towards the AKG Q701 ($200) with a FiiO E10 or a Sennheiser PC 360 ($166) with an additional DAC/AMP. Again, as much as I would love a sound card at this point, I don't have any room in the case.
