Internal sound card for Gaming/Movies -> Music

[a66as]

I am looking for an internal sound card in that order, i would have just got a Xonar essence STX but they are no where to be found or are either too expensive. This is for a new beast build i am doing and its the final part, i'd like to spend less than more (unless its worth it). ill be using my Fidelio x2 and HD 599 with it so it needs to have an headphone amp. i was looking at these sound cards

Sound Blaster Z
Sound Blaster X AE-5 (the new RGB one)
Sound Blaster ZxR (would rather avoid this due to the ugly wire)


Does anyone here have any experience with them or could anyone recommend me a better solution that doesn't cost a fortune? i would like game and movie immersion but i admit i do prefer using 2.0 in games over surround sound.

i actually forked out for an asus essence stx 2 it does sound clearer and better in music but i havn't really tested it in games. I was tempted to try the sound blaster X AE-5 but heard bad things about it such as drivers not working properly and sound dropping out.
