Is my PSU enough for the new AMD cards?

I posted yesterday about my friend getting a new setup, but I'm currently using this power supply

I notice that the newer cards say 600w minimum. I've never really understood the whole volts on a rail calculation, so I pretty much rely on you guy's opinions. :)

I can only convince my wife to go for something around the $300 range, but that beats paying the $400-500 that I was going to pay for next gen(plus the subscription fees..ugh). I'm really wanting a 3gb ram card, and I'm not opposed to Nvidia, but they seem quite more expensive.

Thanks in advance, and I always choose a best answer so no worries!
