Conclusion
It doesn't appear much effort was put into developing Gigabyte's GeForce GTX 1070 Ti Gaming 8G. The card's one advantage would have been a custom-tuned BIOS, but Nvidia obviously took that away just before launch.
What we get, then, is similar performance as the other 1070 Tis out there. No surprise. And really, that may have been all Gigabyte was trying to ensure in the first place, demonstrating what Nvidia's board partners think about this placeholder card, which can't even be factory-overclocked. Nobody's really eager to try something new or innovative with such a locked-down piece of hardware.
Gigabyte's approach may be just fine for gamers looking for predictable performance at 2560x1440. The GeForce GTX 1070 Ti Gaming 8G is fast, light, armed with a semi-passive fan mode, and good-looking. Interestingly, it's only a little more than half the weight of Zotac's GeForce GTX 1070 Ti AMP Extreme. And yet, it's no noisier or slower under load. Thanks to that semi-passive mode, it's also completely silent at idle. Zotac doesn't give you similar functionality.
The only obstacle Gigabyte needs to overcome now is its comparative pricing. GeForce GTX 1070 Tis start at $450, and we'd expect a model built with GTX 1070 parts to show up around that level. Instead, the 1070 Ti Gaming 8G sells for $490, or about $10 less than the cheapest GTX 1080. Really, it's hard to recommend any 1070 Ti in such close proximity to the next step up in performance.
