[Things change I've changed]

So far it seems the Windforce is the card to get it, everybody seems to have a positive impression of it, hopefully the Asus has some good results tomorrow as well.

Gainward reference cooler model.

You going to grab a Windforce instead?

You would need an IVY bridge or SB-E cpu to use PCI-E 3.0 as well as the mobo.

Oh i see. So is there any pcie 3.0 mobos compatible with my sandybridge?

 

[Cuchulainn]

I expect so yeah, or potentially the Asus....

what about the z77 boards?

There is really no need to upgrade to PCI-E 3.0 atm, it will net you about 1 frame, these gpu's don't utilise the extra bandwidth from a PCI-E 3.0 slot.

Forget this stupid question please i just googled the answer

Well I don't think it makes much difference as one review I read stated the asus direct cu 670 was hotter than reference.

Internet armchair engineers are awesome.... Something is poor because it "looks it." Dribble Dribble, Drool Drool.

I'm up later than planned, just getting my act together then its onto watercooling

 

[Broken Hope]

Mine is going back. Had enough of the fan noise. Ludicrous.

I've actually done the same now, gone for a Windforce as a replacement.

 

[vandiesel]

What happens to all these returned, used DSR 670s?

Become 'B' grade at a knocked down price.

Check OcUK's clearance lines.

Not sure what problem is here but most games my 670 windforce reaches 70 but never goes above that, fan on auto. Airflow is great and case feels icy, confused.

There's not a lot to be confused about. The 28nm GPUs use MUCH less power than 40nm therefore create much less heat.

The GPUs still hit around 70-80c but because the chips are a lot smaller much less heat is dissipated into your case.

it may be cos it's early but im sure your contradicting yourself, they still knockout 70-80 despite using less power because there smaller, so how does that justify a cheaper/smaller heatsink?

No... He's right.

Smaller chip at same temperature = lower heat output and less energy to get to that temp required, even if the temp is the same.

Oversimplified... But think of radiators... You have two at the same temperature... One the size of your wall, the other the size of a small fireplace... Which is going to heat the room quicker and take the most energy to get up to temperature in the first place?

adding my 2c...

I had an EVGA 670 SC that was faulty ootb - driver crashes and artifacts at stock (manufacturer OC) speeds. Also the fan noise was annoying at idle - I don't have any objective measure but to my ears it was a mid-pitch whine that got worse on load.

Swapped to a Gigabyte 670 Windforce and am much happier - almost silent at load and the sound is much less grating. Just testing at stock at the moment for instability or artifacts but so far so good.

got it but by thinking of sparklers

Hehe

Guys, these cards are not different to how things have always been. Lets say you have a 5770, you whack the clocks up 1200mhz, voltage up to 1.2v, leave fan on auto and run Heaven. Lovely old job you think, Heaven seems stable with no issues and then you open GPU-z and see the temps.... 90C and steadily rising and the fan sounds like its going to blow your PC across the room.

What are your options?

1. Increase fan speed for more noise, or decide on an aftermarket cooler?
2. Lower voltage and therefore clock speed as your GPU becomes unstable?
3. Pray to Jesus that it will stop soon?

Most will pick option 2 as that is better for your ears in everyday use. With the 680 this step is automatic so the only option you have is 1 but at the end of the day you still have an option, and best case is it will create only 2% higher clocks anyway so most will do nothing. Find a boost that is stable in all scenarios and stick with it. Simple.

 

[~bones~]

Well just sent my KFA2 back on DSR and ordered the windforce, will let you guys know what the difference is like

price gone up to 380 pounds for the asus directcu, are overclockers taking the **** ? can literally get the same card for its excluding vat price (but including vat). its not even the top version.
