GTX 1060 and 1070 aren't dead. And welcome the new GTX 1070 ti.

Ah, the GTX 1080 ti. The mac-daddy of graphic cards to date. It's capable of fluid 4k gameplay with impressive resolutions at a premium price, ranging from $750 to $850. It really is on another level as far as graphic cards go. Enthusiasts will surely plug one of these into their setups for some ultra setting gameplay. For the rest of us there's the rest of the GTX family.

If you need a card that can handle the games at a 60+ frame rate at 1080p or 1440p without breaking the bank, then turn your attention to the GTX 1060, 1070, or the soon to release 1070 ti. These cards are still pumping out fps on today's releases. Check out toptengamers.com GTX 1080 vs 1070 vs 1060 benchmark data.

With the release of the 1070 ti we have another high end card for a mid-range price, starting at $449. It's just shy of the 1080 in CUDA cores count at 2,432 versus 2,560 in the 1080 but uses GDDR5 instead of GDDR5X. The best time may be now, to join the GTX 10XX family if you haven't already. A second hand GTX 1060 can be found for just over $200 or around $300 for the 1070. For the price they're very viable options.

If you're fine without the latest and greatest tech in your setup and you're comfortable with eBay stick to a model or two behind the latest and greatest and upgrade when you feel it's necessary. Try focusing on some quality base components and get used to swapping out graphic cards every few years. A 980 ti on ebay can still go for over $300. If you put that into a 1070, it's almost an even swap. 

If you were on the fence about which card you should buy it's safe to say whatever choice you make you'll be in good standings. Focus on a strong foundation with longevity and think about brokering those graphic cards.
