I am not sure why people are saying that the Vega Frontier card is not for gaming... It is nearly 100% marketed towards the Titan Xp crowd. Which is a combination Gaming/workstation card. That is what this is. I will probably get slammed for saying it is a "gaming card" is the same right as the Titan because AMD fans are very super protective, but the marketing of this card is 100% consumer/gamer who does prof. work on the side. The colors, the metal shrouds, the fancy looks, the ads, the marketing all screams Titan competitor. Nvidia also claims that the Titan is not a gaming card btw... even though it is used for gaming primarily. I expect this to be little to no different. Even the pricing of the air cooled version is competitive with the Titan Xp. The water cooled "gold" card is a bit ridiculous though... much better to get the air cooled FE card, and spend the $600 saved between the two on a complete custom water cooled loop with huge rads and blocks for the CPU and GPU with the $600. That kind of money will get you a pretty awesome custom loop.
This is the Vega answer to the Titan Xp. It will do gaming, and it will do professional apps.
There have already been benches released/leaked on both the gaming and professional performance.
The Vega FE is slower than a 1080Ti for gaming, but faster than a 1080.
The Vega FE seems to be beating the Titan Xp in professional application use though. So... its a trade off. If you care more about professional work performance, and less about gaming performance, than the Vega FE is for you.
