The power usage on the new GPU's isn't much greater than the GPU's or 2 - 3 generations ago.

I would imagine you would probably be ok if you haven't had any issues with your current GPU.

Should wait for HD 6000s. They'll probably be half the power consumption of a GTX 470 and even surpass it's performance.
