Question Sound card died, how to replace it? (it has to feed a HD600, 300 ohm)

[Indiana]

Basically what the title says, my sound card died, or something like that, and Im looking for alternatives to power a Sennheiser HD600, that has 300ohm, which means I need some sort of amp I guess.

I used to have a Asus Essense STX II.

Thanks!

(I have a gigabyte b85m-d3h motherboard, not the best audio chip for what I understand)

What's your budget?
