That's actually completely backwards, most benchmarks for high-res setups (4k, Eyefinity/Surround) show the 780Ti pretty much always beating the 970, and even the 980 on several occasions. You really have to think of the 970/980 release as refined replacements for the 780/780Ti and NOT upgrades, because they really aren't, they each provide rather unremarkable improvements over their predecessors (especially when you aren't even hitting 3GB of VRAM usage). It's only for people who are on lower-end cards like the GTX 5-600 series that will see HUGE improvements in both performance and power efficiency.
