And you won't need another more powerful power supply to run 2 cards.
2 GTS 450 draw 200-220 Watts, and since you are overclocking the CPU and the pc has got multiple hard drives and several other components, 650W could be not so much.

However, in your case a 650W PPU would be fine for the GTX 570
