The reason this method works so well with ribeyes is because of their fat content...the top half of the steak is very well marbled.
NY Strips will work, but will take longer to cook.
Personally, I just poor-mans sous vide the steak, and after it's done to my comfort level (usually 130-135 at 2 hours), I just throw it in the pan for an ultra-quick sear (30-40 secs a side MAX) and that's it. It works with pretty much every single cut of meat out there. You just need to have a good vacuum sealer and a drink cooler.

I'm lucky in that the water out of my tap comes out at about 135..I don't start adding hot water until it hits 129. 132 is my aiming point, but up to 135 is ok. If you brim the cooler with water to temp, it holds onto the temp much longer. I usually only have to add water once, maybe twice, during a 2 hour cook. I usually check the water temp every 45 minutes, give or take. Starting with a steak just out of the fridge will require more maintenance than a steak that's at room temp before throwing it into the bath; in that case, I'd check every 20 minutes until it came to temp (around 45 minutes ot so)
I didn't say it was faster...just that it was better and required less maintenance from you :)
