Would u rather get 2 5870s or a 5970?

^why not two 5850's then?
i think there are still hella(lol) fast and out of the box maybe the same a 1 5970 in real world

 

id do a single 5970..(and to the person who said they arent two 5870's..they are..just down clocked and under volted)

 

2 5850's on the egg at least for the next few minutes

Well I have a 5870 and a Phenom 2 955 was overclocked to 3.9ghz but now Iv stuck it back to stock 3.2ghz and all I can say from running games on my 5870 because I have a G15 keyboard I can see in real time what usage the games are taking and its around 48% plus been running some benchmarks just and the last one I ran was street fighter 4 and all it was taking was 38%.

Plus my monitor is 1080p plus if I run DX11 benchmarks my CPU is around 10% and AMD DX11 demos my CPU is 0% that’s right 0% so yes 2x5870 would be easy for the Phenom 2 and more easy if overclocked plus don’t know if any body else thinks so but for DX11 the CPU is less important because of the compute shader because when running the AMD lady bird, mecha demo the CPU is not even been used to 1%.

Hope that helps.

 

I would not get any of them untill more game use DX11 and by than those card will be too slow to run DX11 game like it meant to be play just like DX10.

 

If money were no object I'd go with 2 5970s in crossfirex for quadfire.

As it is I'll probably scrape up enough to buy a second 4870 and go crossfire.

 

Ok gurus I have changed my mind it would be 2x5870 only because there may be a overcloking issue with the 5970 when it gets to hot it pushing its core clock down to 550mhz plus it does it on stock have a look for your self in this review I found here:http://www.legionhardware.com/document.php?id=868&p=1

If its true can you imagine it playing dirt2 because its dx11 it be taxing the GPUs like crazy and the frame rates while you playing will be up then down:bounce: then when its cooled back up then down again sorry but no thanks!.

As any body here got one of these cards if so do some benchmarks and see if it does.

 

I didn't read the entire article but it seems like they only testing with Furmark? That puts more load on your card than any game would, even DX11 games. Besides, I don't see the issue. Extreme overclockers will probably resort to water cooling.

Not true. We've already seen performance in some DX11 titles and 5800/5900 series run great. In fact in some cases DX11 runs better than DX10.

 

none..waiting for nvidia

 

They was testing stalker and they noticed the card dropping the core speed on that game even not overclocked so can only imagine what proper DX11 games would be like with the compute shader being used that would be something that would annoy me and I just could not live with.

But I agree if you water cooled then no problem but people who don’t it be a nightmare in the summer on a hot day.

Good for you better like waiting as by the look of it, it be a long wait.

 

A HD5970 is nothing more than a HD5850x2. With that said, if money was no issue I'd rather go for 2 HD5870's. But since money is an issue, and because I want to go TriFire for Eyefinity, I plan to get a HD5850 and HD5970.

 

Could be March next year! Then again you have got 4 gpu's! lol

 

a 5970 is 2x 5870, not 2x5850. a 5950 is 2x 5850.

 

2 5870s

 

Completely wrong. The 5970 has the same amount of stream processors as the 5870, while the 5850 does not.

The 5970 is an underclocked 5870, that is all. OC'ed to 5870 stock speeds and presto, it's a 5870x2.

 

In every right it's basically a 5850x2 due to the fact that the clock speeds are exactly the same as a 5850. Those extra few stream processors aren't going to make a bit of difference.

 

The stock speed of a 5970 seems pretty far off from a 5870. IS there a possibility that it can be OC at that speed and take note 5870s will be OCed much higher.


I understand the reason why they lowered the speed is so it could fit into regulations for pci-e devices which could not exceed 300W correct?


In any case i am sure ppl will be pushing their hardware regardless of a 5970 or the 5870. It would be disappointing if the 5970 could not OC to the stock speed of a 5870.

 

Quote for truth

 

In shader heavy games there is about a 10 % difference at same clocks. So imo, yes they do matter in games like Crysis where every FPS counts.

I'm pretty sure a 5970 will clock just as high as a 5870, but only on water. You're going to get better air clocks out of the 5870, no doubt.

 

Uhm, there's not even a 10% increase in stream processors...honestly the difference is too insignificant to be of any worth, so I don't know where you're getting that number from. Also, even if you could OC a 5970 to 5870 speeds, the 5870 could just as easily OC that much more.
