Well in Dirt and Grid your old GPU would have been 60+fps all the time anyways so even if you gain the extra FPS it won't make any difference to smoothness you see on the screen (assuming the CPU is not the bottleneck here)
Bad Company show's a extra 6fps in that link up above so i'm not sure you'll notice that much neither as according to that review a 5870 should run it 64FPS average maxed out at 1920X1200 & 4XAA. You game at 1920X1080 so it should even run faster than that.
P.S i'd do a fresh install as the GTX570 should be faster but like I said before the 5870 may handle the CPU bottleneck better (assuming there is one)
