What gfx card will my psu be good enough for?

[Voltage]

Enermax Liberty 620w Modular Power Supply

Thinking of getting a 4870 x2 or a 280

Currently running an 8800 Ultra, 2 hard drives, sound card and cd drives and the mobo/cpu.

I think you should be fine for the 280 but you may want a bit more for the 4870X2.

As long as theres sufficient current available on the 12v line it'll be fine, I'm running a pair of 4870s in Xfire with a corsair 620w modular.

should be fine for the gtx280
maybe need a bit more for the 4870x2

Should be fine for an X2 if the guy above is running 2x 4870's in Crossfire on one.

As above that psu should be fine for both 280 and 4870x2.

Also AMD site shows an Enermax 625w PSU supports a single 4870X2.
