Your point is valid, just too many dx11 games in tpu bench suite.
I have a similar problem, I want to upgrade but these 2 Gpus are a sidegrade I don't care about and 1070 is simply too expensive, I'll probably never buy a gpu higher than 350€ as 200-350 always was the sweet spot for semi highend cards. I won't pay a big premium for garbage that didn't make it to gtx 1080. I can wait, prices will go down.
I'm kind of in the same boat right now. I simply refuse to pay a premium for Pascal when it is nothing more than Maxwell with higher clocks and lower power use. Fuck that. I want actual, tangible performance increases, and GTX 1070 is going for a similar or even higher price than the still slightly stronger GTX 980ti. Add to that the fact that Pascal AND Maxwell have a weak performance on the newer APIs and my only interest right now is in AMD's upcoming high end. Nvidia is overcharging for 14nm and they know it, anyone contesting that needs a history lesson on price/perf shifts between generations. Meanwhile GTX 1060 will once again be a hamstrung card as we can already see by VRAM ór shader power, and this is also quite close to the norm for a Nvidia x60 release (there's always some shit holding it back too much and you'll feel underpowered within 6 months of release). Where AMD offers a very well rounded RX480, Nvidia offers a rag-tag 1060 tied together with duct tape and a few memory chips with Auto-OC pushing it to its limit out of the box. Noty.
Meanwhile, I've got a 780ti still going pretty strong and more than sufficient for 1080p, even at and above 90-100 fps given some tweaks that hardly impact the visual qualities of the games I play. Most new titles that are big on graphics are 'meh' in terms of gameplay so I'm not too worried waiting abit or tuning settings down for a while.
The marketplace is notoriously unhealthy for anything above the 250-300 dollar mark, and buying into it now is going to be a huge regret later. Already you can see the 1080 which is supposed to be the top dog (I disregard Titan because, well, it's the worst price/perf you can possibly get into) that gets totally SWAMPED in a game like Deus Ex that relies heavier on new API features and a newer engine. The 4K card... and not even a comfortable 30 fps minimum can be extracted from it. There go 700-800 euro's worth of GPU for you. Let's face it. 1080 is a money grab and its a shit card for 4K in the near future. Deus Ex tells us this story and the vast majority of other new API based games support that fact.
It also tells us the Fury X is once again making waves. I might pick up one of those and wait for the real deal sometime next year.
About the bench suite... I don't feel it is hard to draw your own conclusions based on the games/APIs where AMD is stronger and where it is not. It's easy to see and doesn't require a bench suite overhaul. If we let Wizz do all his testing only to have a quick look at some bar charts... I'd hate to see him waste even more effort overhauling the suite. We just need to start reading between the lines, as I do above. Also, the reality is that the vast majority of the gaming market IS STILL DX11 and a bench suite is never meant to be some wishful-thinking projection of our 'future' (we have AMD for that
), but a reflection of the games we play today.
