i think i have answered this b4, a DAC doesn't slot onto your PC Motherboard and doesn't have a USB (well some does). But basically they does the same thing, which is to convert sound from Digital to Analog to be feed to your amp.
Yes a dedicated DAC should performs better as you can isolate the power supply to draw from a power bank which is alot less distortion and noise, while the soundcard has to draw the power from the power supply/mobo which is prone to ripple and noise injected to the power.
edit: no i don't suppose you'll hear much difference on normal speakers, you need hifi where the source, pre-amp, amp's power are isolated to fully utilised the DAC. In those setup, even different RCA cables gives different results

Oh really? I din see any thread explaining this. Sorry for making you to explain again.
I saw some many LYN members are selling DAC like Yulong, Zero, iBasso. What about those DAC? They have USB connection as well. What are those USB connection for if DAC is connected to its own power supply. Some DAC has amp in it as well right? I am a noob in these stuffs. Get really confused reading those threads sometimes
How do you define normal speakers?? Speakers like Aego M, MX5021, are those normal to you?
I am planning to upgrade my speaker( eg Aego M, MX5021) but dun noe whether should I buy a good soundcard or a budget DAC around RM400-600 I guess.
So need some experts to give me some opinions.
I use my PC audio system more for movies/TV Shows/animes than music and games.
