Will the graphic card in the Asus G73Jh last for at least 3-5 years?

So I'm headed for university soon and I'm thinking of getting this gaming laptop. What do you hardware geniuses think? I'm a hardware noob so I know nothing. If this isn't the the best for my price range (USD$1200-1500) what are better alternatives? I'd prefer graphic cards that could last until I graduate. I'm pretty much worried that if I buy one with an old graphic card, in the near future the next game gen comes up and would render my current hardware obsolete. I'd probably spend $100 more if it's worth it. THANKS!
