Hi

Just as the title says i am looking for a soundcard and i am wondering which one i should buy (... if any)?

My specs are :
Mobo : asus m5a97 R 2.0
Sennheiser 330's
Xfx 7970
Some asus network card

Now it gets a little more complicated because my 7970
Is very close to my pci slots and i am afraid that the heat from the card (although it has a rear exhaust) will ruin any sound card i put in there.

(Will update the post with pictures when i get home)
(Sorry if this is the wrong category ...)

EDIT :
Anyways here is the image showing the tight space that i mentioned and the networks card

Solution
there are researches all over as well as on toms hardware . . a basic user can much distinguishes between built in and afternarket cards . . in asus motherboards they usually have amp booster for headphones . .
Well it is moslty because i have read many positive reviews about the sound card that i have been considering the most (xonar dg for instance)
The headphone amp on the xonar dg looks promising aswell?
