43FPS, AMD Fx-55, 2GB ram, Geforce 7800. Either way, this is a ridiculous amount of polygons, so I wouldn't fret if your getting lower FPS/choppy camera. Surely not a 700% increase though. Even from 6.31 > 6.57.b > A7. Although A7 will be worth every dollar, as any speed update, even small, is worth it(never mind the other features).
