Also an Asus Xonar DX or D1 sound card (used, $60), with an external headphone amplifier, like the Magni or O2, would give you a volume knob right at your finger tips, plus the external head amp can be used with more then just your windows PC.
I like hearing that about the STX, however most people on this forum seem to disagree with this soundcard being used for the dt770 or any high impedance headphone for that matter. It's left me totally confused.
Here's some threads that I've found: http://www.head-fi.org/t/454480/would-a-xonar-essence-stx-be-able-to-power-a-dt-770-250-ohm and http://www.overclock.net/t/1001916/dt-770-pro-250-ohms-for-xonar-essence-stx.
I'm actually leaning towards the DT770 pro 80ohm edition now, so that I don't have to worry about the amps anymore. And this thread: http://www.head-fi.org/t/498545/dt770-pro-250-vs-80-asus-xonar-essence-stx
An Asus Xonar DGX is said to drive them well, and it's really cheap too. Although I'd like to go for something better in case I upgrade in the future, but my thoughts right now are that I need to get some experience to know what I actually want. I think the DT770 will do me good as I'm a bit of a basshead, and I don't know the differences from 80 and 250 ohms, so I will just try to avoid the amp and get the 80 ohms... although to mess with my head even more some say that you still need an amp for 80 ohms. Totally confused right now, I must clear my head.
