Is there a difference in sound between these two? It would be a convenience for me to use the sound card but if the difference will be large enough to notice I might go with the dedicated amp+dac.
OMEGA Claro Halo sound card or magni+modi for akg q701 headphones?
Do you play games with surround sound or watch DVD/Blu-ray movies on the PC?
Or is it just for music audio?
Guess Magni+Modi would be the better choice.
At least with external audio, your not affected by any electrical noise (if there is any) from inside the computer case.
I actually decided to go with the shure 940s instead. Will there be any noticeable difference between the soundcard and the externals sound quality wise? A card like the omega claro won't have any electrical noise if it's working properly.

The Shure SRH-940 are only 42-Ohm. so the Magni amp has a slight advantage, as the Magni headphone output jack impedance is very low (> 1-Ohm?), lower then the Claro sound cards 10-Ohms?

You want (it's recommended) the impedance of the headphone to be 8 to 10 times the impedance of whatever jack your plugging the headphones into.
Otherwise you might get problems, like a bloated bass.
A $60 Fiio E11 portable headphone amplifier should be able to drive the 300-Ohm Sennheiser HD800 headphones.
An $80 SBZ (Sound Blaster Z) should be able to drive the HD800s
My Essence STX sound card ($175) can drive 600-Ohm headphones, so a 300-Ohm headphone would be no problem.
Sometimes there is electrical noise inside a computer case
So going with an external setup (Magni + Modi) will keep your DAC & amp. from being affected by electrical noise (If your computer has a electrical noise issue).
Using an external USB DAC like the Modi means your not going to get headphone surround sound for games and movies.
As USB connecting bypass the computers sound card.
If you get an external DAC with a S/PDIF (optical or coaxial) connection, then you can still use the motherboard's built in audio features,
or a sound card with an optical output.
After some calculations I have about a $300 max budget for a dac+amp. I read somewhere that the modi dac isn't that great for the hd800. I'm thinking I might go with a magni and a $200 dac if I can find a good one somewhere. Any suggestions? 3D sound doesn't matter much to me I just want my music to sound good.
I have the O2 (Objective 2) headphone amplifier, works fine with all my headphones.
