Me mate just got for a new system. Anyway the motherboard has failed and we tested the 570 in my system to make sure it worked. I benchmarked it and it pulls the same score as my 480 in my system. The 480 was $600 at the time the 570 is $470 now and a 580 is between $750-$1000. value for money is on the 570 been a very good card if anyone is looking.
I even thinking to sli 2 570's and move the 480 on. cost me about the same and draw less power for same frame rate.
