Yes, this isn't the most accurate benchmark tool but it's pretty good for reference. It's not accurate because they use stock or reference models of the cards instead of the Board Partners (MSI, XFX, Sapphire, EVGA, etc.) aftermarket versions. You'll see in this comparison that the 7850 is better in Crysis and Metro but the rest of the games go for the 570. The 570 does consume a lot more power (still be fine with your PSU) and because of more power consumption and both having relatively the same thermal design the gtx570 would run a little hotter but would not be a problem with a well ventilated case.
