should i open an IRA? or Roth IRA? what return can I expect 25 years from now?

I recently learned I can contribute up to $5,000 to an IRA. In 2012 I was in the 15% tax bracket because I only worked a 4 months of the year. In 2013 I expect to be in the 25% tax bracket. I am 24 and have no current investments.
I heard from friend i should put $5,000 into an IRA and take the tax benefit $5,000x15%= $750 cash back now. I am considering this but was wondering how much exactly can I expect the $5,000 to be, 35 years from now, when I am 59. If I can't touch the $5,000 (with the limited exceptions) is the $750 benefit now worth the cost of not having access to the $5,000 for 35 years!? [assume i never intend to purchase a home and live in an apartment]
