6850 CF or 5850 CF or 460 SLi or GTX570

post #1 of 11
Thread Starter 
Have a couple of options I want to explore. Currently I have a 5850 and can probably pick up a used one cheap. Which of the mentioned dual GPU setups is the best performing one?

Personally I would probably go with a single GTX 570 because I prefer to have one stronger card over two weaker ones, but some of the other setups would perform better.

The 6850 is a weaker card than the 5850 (yes, that's how AMD decided to name them) so switching to two of those would be pointless. So you can rule out that option.

Switching to two 460s would be better than your current setup but probably only about equal to having two 5850s in CF (the 5850 is a stronger card but the 460 scales a bit better). So I would rule out that option too.

So that leaves you with the option of buying a stronger single card (you also have the 6970 to consider as this is similarly priced to the 570) or getting a second 5850 for CF. The two setups would perform similarly, with the 5850s possibly performing a little higher. But then you have drivers, heat, power consumption, and PCI lanes to think about. Of course, a second 5850 would be a lot cheaper. So it's basically up to you to decide which one you'd prefer.

I had crossfire 5850s, 6870s and now I have a 570. I can tell you from first hand experience that I love this card, I do not regret the "slight" downgrade at all. Definitely go for the 570.

I, personally, would go for 5850 crossfire. You can get on really cheap now-a-days.

Cool thread. I have a 5850 and I'm currently thinking about this as well. I'll be following this.

Also just as a side note. The HD 6850 crossfired in most cases will out perform the HD 5850's in crossfire. They scale very well. But if you have a shot at the GTX 570, get it!

I personally would run with one stronger card aswell as stated above. Less heat, less noise less hassle to deal with. My 02

Thisis what I did. I bought two Asus 5850 DirectCTU Top for a total of $220. Tehn I overclocked the cards to 950/1200 @ 1.260 vcore. I did not notice any problems with crossfire. However BC2 crashes just as often as with my GTX260 SLI cards.

Cheapest route another used 5850. Wish list route, 570 with another down the road.

GTX570 is a good card. 5850CF is a faster combo though. I ran 5850cf with no issues and would do it again.

I won't recomend the 6850cf since I just returned a 6870cf combo that ran like crap. I used to think people who talked crap about ATI drivers were wrong. ATI drivers suck for the 6870cf combo at least.

I also ran a 460sli 768 combo with no issues. I would also recomend this combo. Great performance, slightly slower than a 5850cf in benches. Can't tell real world.
