No you were wrong mate...look again carefully.
Benchmark says GT 440 DDR3 got 49.3 FPS and 5570 512 DDR5 got 50.81...
The setup which is on the top of the list is GT 440 SLI which has 79.38 FPS
And according to this 5570 would be better than 440 http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html
But my 5570 is a different cut down version so I can think GT 440 is better anyway
