That sounds pretty good. Honestly tore my GTX550's a new one. With settings like that I only run about 40FPS or so. With the settings maxed out, I don't score very well.. the AA kills myGTX's 192-bit memory bus. But with AA completely off I don't score too bad.
And yes, Heaven is the best I've used in quite a while!
Glad you are happy now. And don't feel bad.. That setup even brings a 7970 to it's knees.
