Pain wise it depends on the person.
For me, I had all 4 wisdom teeth taken out, two were impacted and had to be broken up, and I was up and about as soon as I woke up from the anaesthetic. No swelling, not much pain and had no problems eating/drinking liquids the same day.
However, my sister went through the same thing and was in bed for 3-4 days and was unable to do anything except sleep and lie down.
As far as snowboarding goes though, seems like a bad idea to do it so soon since you'll still have massive holes in your mouth that will still be clotting and healing. You're meant to be avoiding strenuous physical activity while the hole heals up, so it's not really an issue of pain, but just the healing process requiring time and low impact activity.
