Best GPU for a 500w PSU?

Hello people :)

I currently have an Antec Sonata III with a 500w PSU. What do you think is the best GPU that can work on it. It's a good quality PSU;Antec Earthwatts EA-500 (80+ certified) and has 44 AMPS on +12v rail. I'm thinking of getting a 5870 but do you think my PSU could handle it? I only have a 1x PCI-E 16x slot so no multi-GPU solution for me.

5870 I would say a abit much more a 500w psu , as psu's age they lose their ability to produce the same amount of power. A GTX 460 would work nicely on that psu.04dcarraher

Whats your CPU? Getting a high end GPU would be kind of pointless if your CPU bottlenecks half its potential. Captain__Tripps

When will it be released? I'm planning to buy my Rig at early November. :P
