I recently purchased an ASUS GTX 770. I plan to build my gaming PC starting the end of this month or early next month. I will be playing games such as the Crysis trilogy and Mass Effect trilogy on high settings at 1080P. I will also be using this card with Flight Simulator X since I am currently in flight training. Even though the motherboard, CPU, and GPU are overclockable, I don't have any plans to overclock at this time. I am looking at replacing this GPU at the earliest anywhere between zero and six months after the GTX 900 series is released (between 18 months and 2 years from now). But based on any pc gamer's past experience, how long should this card last me when playing games on high settings?

My 7970 is 2 years old and has been overclocked to hell. Now I have generally found my AMD cards to last longer, but then again my 6 year old GT 130m still works too! Don't worry!
