If your interface does not work (meaning deliver low latency) in your current OS you are screwed!
Hate to put it bluntly, but there you go.
Why do you think I have an RME UFX and the FW-1884?
I have an old Gina (somewhere), she was great at the time, but alas...
Babyface Pro, Motu Ultralite AVB?
Not exactly "budget" but, "you gets what you pays for".
There are lots of options.
Want low latency, you gotta "put more on the counter than your elbow"; that's what my dear ol' mama used to say.
My BabyFace (damn, they announced the "Pro" just after I bought it,%$#) is just as "low latency" as my UFX.
Good luck!
