Shop for thunderbolt connecting models or some of the higher performance USB or firewire models. A faster interface will let you achieve, for example, a 6 or 7 ms round trip latency with a 128 sample block size whereas a slower unit will require the block size dialed down to 64 or 32 samples to hit that target.
You can't run any plugin live that has a higher internal lag than what your block size is set to. So the faster interface also leads to more and higher latency plugins being able to be used live.
All of this is no matter how fast of a computer you have. You would shut down that $60,000 film house Mac Pro with an errant setup just the same.
For audio in general, shop for fastest single core performance first.
For live audio, shop for a faster audio interface first and foremost.

No way a USB or thunderbolt is gonna be faster than a RME raydat 🤣
