Currently using my Essence STX to drive my DT770 Pro 250-Ohm headphones and I'm not even on the highest power setting.
For $60, you can upgrade the op-amps (operational amplifiers) on the Essence
One option is to get the Asus Xonar DX or D1 sound card (used $50) and spend the rest of your cash on an external tube headphone amplifier.
But I find it so much easier with the essence and everything built into one device.
I own the Asus ST (the version that uses PCI instead of PCI-E, but otherwise the same). I HIGHLY recommend this card for people starting out. It has a good quality DAC and Amp built into it. They certainly aren't equivalent to 'high end' audio stuff, but I think it's one of the best 'bang for the buck' set-ups right now.
As you upgrade, later on, you can add an external amp and use it as a line out, or use the digital out if you want an external DAC, as the digital out is quite good as well!
This card will have plenty of power for your HD650
