Summary is the main part. If he does go that route though, the extra vram from CF may be necessary for 2560x1600.. but thats hard to say convincingly.



You can see that the single GPU shows the 570 ahead at 2560x1600 even with less vram, so the only reason it falls behind at SLI is the scaling. Which can be easily upgraded through drivers, and nVidia definitely has the edge there over AMD. For that reason I'd still get the 570s.

It's probably worth looking into a pair of 6950s. I'm not sure if these particular cards are unlockable but even stock 6950s are great in crossfire.

With the new 11.4 drivers my 6950s (unlocked) were able to come very close to a GTX 580 SLI setup in 3DMark 11 with the performance preset, which is pretty impressive.


You can't go wrong with 570 SLI either though. At 1920x1080 they'll both perform about the same. Personally, I swayed towards the 6950s for price, unlocking ability, and the 2GB of video RAM for Eyefinity.

The 570 beat the 6950 by 4 FPS with the difference of $80+. You must have a fat bank account. Anyways, the 570 is comparable to a 6970 SINGLE CARD which should cover that 4 FPS gap at that resolution.

95% of any driver related issues are user error. A few months ago, when I was using the 8800gt, I had issue with custom resolution. No matter which driver I used the custom resolution for Nvidia control panel will not stick. Try to google this issue and there are several threads regarding this problem. They're probably still not fix as we speak. I also had issue with ATI but found out later it wasn't their driver fault but my PSU. So in all honesty both side have issues but like I said it's more user related error than the actual driver.

Nah, I just like using 3DMark because it's more neutral than games built around Nvidia's or AMD's architecture/Drivers.

Why exactly did you link the SCALING graphs, but forget to mention that even with better scaling.. the AMD cards are still SLOWER overall?
FYI, you're comparing the 6950 to a 570 not the 6970. Since you just remind me... I did forget to mention the 570 is $80 more expensive than the 6950 with the difference of 2%. So if you're going CF with 6950 you'll save $160 with the same performance as a 570 if not better. Is this what you're looking for?

BTW, why does Crysis perform better on Nvidia card than ATI? Just a thought.... maybe it have to do with the Nvidia logo when Crysis start every time. You posted 2 games out of 5 benchmark and one of those games are highly optimized for Nvidia. The other 3 games show the 6950 CF outperforming the 570 SLI. Cmon man give me a break...

I am? You're the one that posted that article. All I did was ask why you linked scaling results, when the performance results were clearly in the nVidia corner regardless of scaling. But I'm the one being irrelevant?

And the OP already mentioned he was referring to the 6970 or 570, with the 570s being the cheaper choice for him.

[edit] And FYI, the single GPU comparison in the performance summary is 55fps(6950) versus 63fps(570). That makes the 570 14% faster... not "2" lol.

Actually if you ever decide to use multi-monitors, go w/ Nvidia. Drivers work better and you'll want all of your monitors connected by the same type of port. There might be syncing issues b/t monitors connected by DVI and DP at higher resolutions.

If you read the whole thread then you would know the reason why I posted the scaling results. It was a response to LivingChampion 3DMark scaling analysis for the 570. There's also a reason why I posted that link so everyone can read all the details w/o it being summarize by myself.

You're not being irrelevant, I thought your argument was very right on point until you nit pick certain benchmark from the link I posted. As you and I know the benchmark I posted is b/w the 6950 and 570. They're about 2% give or take difference in raw performance in SLI/CF (according to that article). Now the topic is regarding the 6970 vs a 570. The 6970 is a stronger card than it's younger brother. If we were to compare a 6970 vs a 570 in SLI/CF then clearly the 6970 would win.

If the 570 is a cheaper choice for him then he definitely need to look into the 6950. Am I right? Would you pay an extra $160-$200 for 2-5 fps.

In my OPINION, a 6950 CF is comparable to a 570 SLI. A 6970 CF is comparable to a 580 SLI. I've seen lots of benchmark done by OCN members and was astonish by the results. Search for the benchmark yourself and maybe you'll see where I'm coming from.

Thread Starter 
Just to clarify further, I get dealer level pricing on video cards. As such there isn't much point in getting 6950's. I can get 6970's for close to the same price. I also look at what they will have for resale value down the road as well.

The 570's and 6970's in a pair each have a price difference of $45.

As such, it seems moot to go with the 570's.

Here's a good review.. The 6950/6970's perform quite flawlessly in Metro 2033
