An 1150mhz HD7970 still loses to an overclocked GTX680
The GeForce GTX 680 2GB overclocked to 1186/7128 MHz is an average 4-11% ahead of the AMD Radeon HD 7970 3GB (overclocked to 1150/7000 MHz) in 1920x1080 and 1-9% ahead in 2560x1600. ~ Xbitlabs
That's an overclock on a reference GTX680 BTW. This means HD7970 would need a 1200-1250mhz overclock to match a reference OCed 680. How much are those non-reference 7970s? Not $499.
Oh and if you want one with warranty similar to EVGA, you'd need to get a $599 XFX Double Dissipation. So $100 more and you need to get a card that hits 1200mhz guaranteed to much a reference GTX680?
Huh?
Those are OC versus OC results and the 680 loses half the time unless i'm reading this chart wrong. Further the 680 doesn't seem to scale as well, but GPU boost muddies the picture quite a bit. In crysis 2 it loses by nearly 20% and Civ 5 as well.
This is why I don't want overclocking to be limited. Any % difference can be more than overcome with an equal OC.
