I run a Q6600 @3.6GHz with my HD4870 1GB on a corsair 520W. Depending on the rails the age and the specific model of the PSU, you could well be fine with it.

My PSU:
SilverStone model no. ST50F
Strider series 500 W, Active PFC.
Cooling System : Single 120mm low noise fan
Noise level : 22 dBA minimum
Weight : 1.80 kg
MTBF : 100,000 hours at 25"C, full load.

sorry 'bout asking many times... cause i'm afraid that if i buy a 4870 and it won't work, that would wasting money...

I can't get on the silverstone website atm. http500! Looks to have slightly less on the 12v rails than the corsair though.

Using the jsc PSU calculator, I get:
CPU: OC'd about 8 amps @ 12 volts - estimated, might be a little high here
Video card: 5 amps at 12 volts
Motherboard: 4 amps @ 5 volts, 1 amp @12 volts
2 GB RAM: 3 amps @ 3.3 volts
HD and DVD R/W: 3 amps @ 12 volts and 2 amps at 5 volts
Fans: 1 amp @12 volts

That's about 18 amps @12 volt (216 watts) and 40 to 50 watts at 5 and 3.3 volts.

Most of these estimates are based on actual measurements.

A 4850 pulls about 5 amps more than your original configuration. A 4870 pulls about 9 amps more than your original configuration.

You should be OK. You won't have a lot of reserve capacity.
