Is the ATI 5670 better then nvidia 9500gt?

[xx_pemdas_xx]

I was wondering if the 5670 1gb gddr5 is better then the 9500gt 1gb Gddr2? I have a 9500gt 1gb and was wanting to know if the 6570 would be enough of a performance boost to justify buying it? will i notice a difference in COBO or SC2? Please nothing about brands. I am not a nvidia or a ATI fanboy i use both brands.
Thanks

Also I have overclock the 9500gt to 650 clock 425 mem and 1600 shade.

yes should be a huge difference, and a worthwhile upgrade. this assumes you have a decent cpu, enough ram, and sufficient power supply

5670 is better by alot. 5670 is comparable to 9800GT in term of performance but use less power than 9800GT. you can look here for graphic card comparison:

some benchmark on 6570 and 6670:
