If you are comfortable overclocking just get the cheapest model.

the middle one has a better cooler, meaning it runs cooler...... i understand the OC it your self, but getting to 1ghz core is pretty hard and the lower the core clock the hard it is to do.

that's what i was thinking about.
i dont know a thing about OC but with some help i might do it.
but anyway, can i get the same core at the end?
or a 950 core from factore can go further than a 850?

That does seem high but 1.4v is fine if you have good cooling. With 1.5v that card should do 1.1GHz.

You are only guaranteed to get whatever clocks the card comes with. My 4890 is stuck at 988 core. If you buy a lower clocked card, you run the risk of not being able to clock it to where it would be if you bought the higher model.
Also, I know nothing about Powercooler. I haven't really heard of anyone on OCN with one of those 4890s.

i'm a 0 about OC. i dont have a pc yet and im trying to make a good rig here on OCN. after that i want to OC the new rig so let me see if i get something already:

to increase the core i need to increase the voltage right?
increasing the voltage will increase the temperature right?
so i need to push the core as far as i can with the lower voltage possible, and that is the secret of OC.
am i thinking right?

Yes. Lower voltages are better for overclocking because they have lower temperatures. Depending on how good the cooler is, you may be able to get a higher OC. A lot of it is luck.

if it starts to heat to much, will it stop at some temperature or will it burn the GPU?
i want to OC my PC when i get it but i dont want to send it to the garbage can on the
1st day i get it...

i like noisy things. noisy cars, noisy computers... so it is not a problem to me. if that one can go further on OC i think i will get 1 of it.
