It isn't the wattage that matters. Its the 12v rails and the overall quality of the unit.
The 500W Antec PSU I had 4 years ago had similar 12v rails (18a and 17a I think) and I was using a much weaker CPU at the time (athlon x2). I can't remember if it was the 7900GTX, 7950GX2 or the 8800GTX that did it (I had them all in a span of 8 months
), but my PSU started whistling and I had to RMA it. I'd never lost a good PSU before that, so I figured it was just overloaded.
Just to be safe, I bought my OCZ GameXStream700W (4 12v rails at 18a each) and used the replacement Antec 500W in another (weaker) system where its been running fine 2 1/2 years with no whistling.
Since then I've been a bit more careful about how much I load onto a PSU, especially if it isn't a good name brand.
If you want to get a new unit musman, there are a lot of options it just depends how much you have to spend. Corsair's PSUs are among the best you can buy, but you're looking at $100 for one that'd be good for your setup.
This OCZ StealthXStream 600W should be good for you though and its cheaper:
