3D Mark bench are 100% legit as videocardz said, so that gives a pretty solid feel for the performance.
price there is no real magic to it $msrp to £ add 20% then add 5-10%, you will get the spot on price, you can apply it to the 10 series.
Actually we don't know that's the problem - too many variables; what bios? what drivers? what speed were the cards at; Videocardz has been wrong or down played things in the past.....I'm not saying they are now; but again we don't have enough information.....
we're not talking just a couple % points here; but 10+% which wouldn't fall into acceptable variable error or difference......
