How long will a gtx 770 and gtx 780 last on max settings?

Solution
Such cards typically have a warranty of 3 years.
Unless you abuse them by overclocking, I would expect them to last until they are obsolete.

So long as you will be gaming on a single monitor(not a 4k), then performance should be good for a long time.

I would expect the i5-4670K to be relevant for a long time, perhaps 4 years.

Past that, who knows what moore's law will bring.

I can't give you a definite answer, and no one else can. But if you're talking about next gen games, and games to come, not that long, is my educated guess.

Assuming 1080p, the 770 is close to maxing out some games, but probably runs better without AA off anyways. The 780 can pretty much max out most games currently, but a few settings -may- need to be turned down.

That being said, future games are going to become increasingly demanding graphics wise. So, if you're only looking at maxing out games, I'd expect a GPU replacement every year. But that's just my take on it. SLI exists as well and will likely max out games a year from now. Hopefully.
