If you have to choose the two above I would go with the XFX.

Go for the XFX, you only have 1 card being powered so 550W will be plenty. You dont need 650-1000 until you start running 4+ cards on your system.

this 5970 will pull alone 400watts

I would get at least a 650watts PSU for safety and efficiency.

You should be fine. I have a 5770 running with a 365watt power supply, and the cards voltage is risen. :P

I run 5970's, and they pull much less than that when memory is downclocked.
More like, 250-300 watts a piece for me, but their cores are overclocked as well.

You should be safe with the XFX.
