How well does the GTX 470 overclock?

The reason I ask is that I have narrowed my choice down to the 470 or the 6870. I am buying a new system, don't have the knowledge to overclock myself, and the system offers a standard 6870 or for £12.77 more, I can get an overclocked 470.

I believe the 470 runs hot and noisey and this is quite off-putting.

Here's my other thread if anyone's interested:

Apologies for starting another thread, however, I am close to making my decision and I feel the other thread's title is misleading. Loads of good helpfull gen in there which is helping me and can hopefully help someone else.
 
Most GTX 470 overclock really well as long as you keep them cooled well with water or crank the fan up, if noise is problem get one of models with custom cooler.

They also scale really well in games with overclock. I have mine running at 850/1700/2000 24/7 which is nice power for the current price.
 
How noisey are they mate?

Which models have a custom cooler? Don't wanna be cranking my costs up any more than I have to lol.
 
On stock air, my two are running at 750 mhz on the core, stock voltage, 800mhz ono is the reccomended highest on stock cooling, youll probably need a voltage increase to hit that sort of speed. They can get a bit loud above 60% fan speed.
 
Not sure what card ocuk will supply in a system, however the models i have are the gigabyte editions you linked to.
 
I'm guessing that one as the only other 2 overclocked cards are 'super' overclocked - this is not what the Viper system specifies.

Would this be much faster than a stock 6870?
 
From benchmarks, the 470 and 6870 are very similair in performance, the 6870 will run a bit cooler and use a bit less power.

Yeah this much I know (I don't know a lot lol). The differene is that the 470 will be overclocked whereas the 6870 won't.

However, I believe that the 6870 is very quiet!
 
Depends a bit, ~780MHz will generally catch up a stock 480 but theres some stuff where a 480 will still pull ahead a little.
 
Its a bit complicated - i.e. at 800MHz your texture fillrate and shader performance is higher than the GTX480 but pixel throughput is still a bit behind so in something that is demanding on pixel fillrate your going to trail it but something shader heavy you will slight beat it. To ensure you beat it all the time you'd have to push the core up around 830MHz which is where a lot of 470s top out - but at the clockrate you'd mostly be quite a bit ahead of a stock 480 due to the massively faster performance in other areas.
 
If your feeling brave you could stick 1.1v on the core and chase the GTX580 :D prolly need better cooling tho than even the GOOD edition.
 
Got my OCUK Value (PoV) one a few days ago, still messing with the clocks.

So far got 775/1550/3600 Furmark/Crysis stable from 607/1215/3350 at stock volts. 800 core was too much - was stable in Furmark but some small graphical corruption in Crysis. Fan set to 70% - prob too noisy for some, but not for me - and load temp is 72°C. Not finished upping memory speed yet and not tried upping volts.

Very impressed so far..
