I don't think the 1070ti is a good price, the 1080 are just about similar price maybe a little more but are a better value at the moment
Okay first you skip on the generation and ignored the 770 why because it proves my point if you skip 2 generations 50% is reasonable. You claim 50% improvement on GTX970 to 1070 was that really the case ... nope Look I know it depends on how you view the stats but the same is true on 1080 to 2080 if you look at the benchmark tools they show they show much higher numbers as well. However if you look at the game FPS which is what most people are concerned about the improvement was 36% before. It maybe slightly less this time but until the drivers, games and card designs have been optimised we wont know for certain. http://gpu.userbenchmark.com/Compare/Nvidia-GTX-970-vs-Nvidia-GTX-1070/2577vs3609 I do agree on the price vs performance but that is expected when the 1080 launched the 970's where still a better value. It is very rare that a single generation will make the previous one pointless. The reason for this is that the software development takes time to get the best out of the hardware. Who knows if the ray tracing feature will even take off. I see the card for what it is the next generation steping stone but also taking a big step in the next level of graphics. Companies have to take a risk now and then if we are to make any big jumps forward. If you have the money and want to jump on that train then yes you take a risk. If you are on a 1080 does it make any sense to upgrade no it really does not. However that should not be a shock but if your one a couple of generations down it does just give the market a bit of time for the price to come down.
20% improve gen to gen? No, that's not even close to the norm. Just looking back recently we have: GTX670 -> 970 was a full 50% improvement. Why did I ignore the 770? Cuz it's still Kepler and was just a rebranded 680. GTX970 -> 1070 was another 50% improvement. That said, the difference with Turing is more like 30% over Pascal. But the large increase in price, along with a more-than-two year wait seriously reduces how exciting these cards are. We've literally gone *backwards* in performance-per-dollar, which is absolutely unheard of.
What you mean is everyone was stupid enough to listen the reviewers on youtube over hyping the release claiming the card to be the second coming of god and then slamming the company when it did not meet those stupid high targets. The 2080 is about is about 20% on average higher than the 1080 and the 2080TI is between 20% and 30% depending on the games. That is pretty much on par with the type of generation shift we always see. Yes the 2080 early editions are over priced but then so was 1080 when it came out that is hardly news. It is no shock that the 1080 still have a place as will the 1070's and 1060's and 1050's. The early tech people with money have bought up the foundations editions at those prices so they are not going to change too soon but expect to see the prices drop over the next 6 months as more 2080, 2070, etc come to the market and hence the last gen will also get cheaper. dont expect an quick massive price drops that just does not happen unless companies need to dump the stock.
I'm thinking that an RTX2070 won't be much faster than this in your average game, especially as this is an AMP card. But it'll probably be £550 just for a basic one. I'm a big fan of Zotac cards and these extreme models are usually top quality. I have had many over the years and they frequently hit big clocks like the best EVGA and Asus models, but for a good 10-15 percent less money than those brands.
