Best Polish city to work as a programmer?

I am looking to move to Poland to work as a software programmer. I haven't decided on a city, but three cities look good - Warsaw, Krakow and Wroclaw. Which city offers the highest salaries for software programmers? Which city has the most jobs available? Any advice will be very much appreciated.

Dublin

Hard to say, difference rather isn't big but probably Warsaw.

Warsaw I think sallary will be better but you are going to lost a lot of time on your way to work or to center

Krakow - computer industry developes very dinamic there, and Krakow is nicer.

It's like anything else. It just depends who's hiring at the time you're looking.
