do i need to get a sound card for home studio computer

Is there a difference in motherboard sound cards? For example, is there a notable difference between a Gigabyte A520M S2H's Realtek ALC887 or a MSI B450 TOMAHAWK MAX II's Realtek ALC892/ALC897? I know that back in the early 00s and earlier the motherboard sound cards were deemed terrible and everyone suggested buying dedicated sound cards, but what about now, in 2021? Is there any point in getting a dedicated sound card, or even caring about what sound card is part of the motherboard? I got the receiver to be able to connect my speakers, and my headphones sounds MUCH better amplified than when I connect them directly to the computer jack. I've then connected my headphones (Sennheiser HD58x, so ~120 euro-ish headphones) and my speakers (think ~200 euro for a pair of dumb speakers connected through regular speaker wire - no bluetooth or anything like that). Right now I have a computer with a dedicated sound card which has a 3.5 mm output jack which I connect to a now 20 year old stereo receiver.

I often listen to music using my computer (both using headphones and speakers), but I'm not sure what the best sounding option is.
