I will be buying my first actual amp (a jds labs atom) but need time to save up for a dac, I have a gigabyte GA-Z170M-D3H (I forget which rev, thinking 1.1) motherboard. RCA jacks are a new thing to me so I don't really know how to set them up but I heard they have a better crosstalk performance than 3.5 mm. Is there anyway to get rca into a desktop which doesn't have it (I don't think it does at least) or should I just plug in a male to male 3.5 mm jack into my desktop? Does the 3.5mm jack just go into any headphone slot in the mobo? Anything special to do?

Im not sure to be honest. Using your mobo as a source is a stop gap solution until such a time as you can afford a proper DAC. The sound quality isnt going to be as good as a DAC regardless of which way you connect the amp,though I dont see any other way to connect the Atom w/o using the RCA inputs.

FWIW the cable I linked was on Amazon for like 9 dollars. For whatever reason its re-directing to a Walmart product that is silly expensive for such a simple cable. Search on Amazon,or whichever source you use and type "3.5 to RCA cable".

In these situations, I doubt you would notice any difference, audio quality wise, between using the Atom's RCA line-input or the Atom's 3.5mm (1/8") line-input.
I think the more important advantage of RCA, in this situation, is the RCA jack being more robust.

If you need to use the sound card features, then at a later date, get a DAC with an optical input connection.

Otherwise you can use a USB DAC (at a later date?)

Does the conversion negate any possible positive benefits of rca?
I doubt there would be any noticeable improvement, 3.5mm input vs RCA input.
