GTX570 twin frozr III SLI or HD 6970 lightning CF temperatures

post #1 of 6
Thread Starter 
Hi, I'm doubting to take the msi GTX 570 twin frozr III for SLI or the HD 6970 lightning for crossfire.
I'm sure the performance will be almost even, but I would like to know what card runs the coolest, and so quietst.
From what I understand, the reference GTX570 is cooler/quieter than the reference HD 6970, but with a non reference cooler the HD 6970 would be cooler. Is this right or completely wrong? wackosmiley.gif I would like to know your opinion.

The problem is that I found only one site that has reviewed GTX570 and HD6970, vortez, but they don't tested the acoustics by both cards or don't mention the speeds that the coolers runs on by load. From what I read, more people are complaining about the GTX 570 noise than about the HD 6970 noise.

you would be mad to buy a 6970 when you could buy the 6950 tf 3 for cheaper, and unlock + oc the crap out of it. likey matching 580 speeds. but then you have an ati/amd card with notoriously crap driver support. on the plus side scaling is ment to be great and you would have 2GB of vram.

on the other hand the 570 will also oc to 580 speeds and beyond, and will have much better driver support. however its priced similar to a 6970 and only has 1.25vram.

noise is a non-issue, you shouldnt even be taking noise into account. they are all loud when overclocked.

personaly the 6950 tf3 is the best buy once you unlock and oc it. it has to be the tf3 tho.
Id also get a tf3 570 for the stronger vrms (power circuitry is notoriously crap on the ref model) if you decide to go that route.

one more thing., if your ever going to sli/xfire down the road, dont get a card with any less than 1.5GB of vram. it quickly becomes a bottleneck with alot of processing power and its a major bummer.

so if you get the 570 -its as a single card solution only

that's not true, a gtx 580 is a lot quieter and cooler than a gtx 480 for example.

Isn't it possible to use both cards VRAM? So 3GB?

 

HD6970 costs €30 more in Belgium.

 

I also read somewhere that you can't unlock the MSI HD 6950 Twin Frozr III anymore. MSI/ATI lasers the chips now.

HD6970 should also run cooler than a HD6950 because it's optimized for it.

 

But thank you for you reply, I appreciate that.

Actually your wrong, the 6950 TFIII has its own FAQ of how to unlock it straight away from msi themselves.

When overclocked they are noisy, but its not that much compared to reference cards anyway. Your best bet would be the 6950s in xfire anyway, though they are weaker but scaling is good and overclocked they are even with 6970s. That while not considering the fact that they can be unlocked. If you want to play it safe, get the 570s, but if you want to gamble get the 6950s (its not like your gna loose alot of fps anyways).

I agree with everything except the matching the 580. It takes a 6970 @ 1GHz to match a stock 580. The card is literally just that much more than most people realize. It's Fermi as I was meant to be.

However, this is the best course of action since you get a killer pair of cards that are more than likely to NOT explode in your face and will offer better performance at higher resolutions. The 570 is an amazing card, it falters in high Vram solutions though, especially with DX11. I say go for the CFX 6950 TF3. biggrin.gif

On a side note, is it bad that every time I see someone abbreviate Twin Frozr III as TF3 that I think it's Team Fortress 3? XD

GTX 570 Twin Frozr III all the way buddy. You can OC it too, which makes it good.
