The first statement was with regards to the current set up. X-firing here will not be a very smart idea in light of future upgrades.
The second one was to say if you have a previous gen vs. next gen option and don't want to shell cash for next gen, then you might as well x-fire. redface.gif

I see most of the posters in here saying crossfire is bad dont actually have crossfire setups and seem to just be repeating what they have read. Crossfire is nowhere near as buggy as people make out. I've experienced none of the choppiness, micro stuttering or other rubbish people who dont know how to properly configure their systems seem to experience. The actual major downside to a CrossfireX set up is sometimes games are not properly supported from the get go which can result in having to wait for either a patch for the game a new App profile from AMD or and update to the drivers. This can vary in the length off time it takes for this to happen. But to counter that what you do get from CrossfireX especially if you were to crossfire your current card is a major performance boost (in the overwhelming majority of games) for minimum cost. As for power consumption the cards you are talking would barely surpass or equal the power needs of a similary performing single card. To also address the issue of heat, it is tru that the top card in the setup will usually increase in idle and load temps but not by a huge amount IF you have a motherboard that has a space between the PCI-E slots and a well ventalited case. Hopefully that gives you a better understanding of what needs to be considered rather CROSSFIRE SUX!!!!111!!! posts.

lol, i get what you trying to say btw, not trying to make enemies here, but couldn't help it biggrin.gif

anyway, the thing with cf, the drive issue is gonna be there for years to come. just look at sli, the tech has been around for what, 7, 8 years now, and it's still bugs quite a lot of users...

end of the day, i stand by my point, it all kind of boils down to money in my view, if the op has the cash, then why not, just grab a 580 or 6970, then be happy. but if on a budget, cf is the best bet imo...wink.gif

5k series plus crossfire setups have all worked great for me with the exception of quadfire setups...

Games that they don't work well on are either brand new and CAPS fixes, or they are old enough that they still play great even if only using one card.

If you have 500+ dollars to burn, I agree that one 580 is less troublesome than two 6850s. However, new cards are going to be coming out at the end of this year. Depending on the games you play, the PSU you have (powerful enough for xfire), the motherboard you are using (does it have dual 8X PCI-e slots that would not put the cards on top of each other), you can xfire 6850s by picking up a second at newegg right now for 125 after rebate. Yes, it does have its downsides, but I run crossfire and I don't have anywhere near the complaints a lot of the people here have. Google your favorite games benchmarks with dual 6850s and compare them to a 580, if it will do the trick, save 400 dollars.

Edit: For instance, if you play BFBC2, xfire 6850s are better than a single 580 FPS wise

Bah, I hate the comment, "Why would you crossfire now as you could get a single card better than both."

If people really believe that drivel, then you would never Crossfire or SLI unless you already owned a 6970 or 580 respectively. OP, I won't lie to you, people do have problem with multi GPU setups, whether it is a 6990/590 or any two single GPU cards. But the people telling you all about driver issues etc are wrong. If the technology was that bad, neither NVidia or AMD would be offering it. Admittedly Crossfire was terrible in it's roots before the tooth bridge connection was available. Also admittedly, Crossfire/SLI scaling in new releases can be buggy at times. But to make it out to more than it is is sheer folly.

I've owned and SLI'ed GTX 465's and two 9800GT's before too, so I know whether the grass is greener on the other side. So my opinion is as unbiased as an opinion maybe when I say go for it. All these people telling you a 580 for less power consumption are full of crap anyways. IIRC, and I'm fairly positive I do, the PSU requirement for a 580 or 2 6850's is the exact same: 600 watts.

Crossfire is a great way to let your aging GPU knock around for another year or more. And this close to the 7XXX series release (NVidia's 6XX series will be late to the party), it would be foolish to buy a 580 anyways IMO. You haven't posted any system specs, but I'll assume your planning on gaming at 1920X1080 or less. At that resolution, two 6850's would let you crank through any titles you want to play whether it is Metro, Crysis, or (most likely as we don't know official requirements yet) BF3.

The microstuttering you hear about is not something, I'm affected by, but screen tearing is. However I only see screen tearing in Eyefinity at 5760X1080 and there are workarounds for that.

So yeah, I recommend crossfire to you. Two 6850's will stomp a single 580 anyways. Hope this helps.

My opinion is best bang for your buck or budget is get another 6850 since your half way there.

Most games coming out today do take advantage of crossfire/SLI so that's not a problem.

I upgraded, for a very brief time from one to two AMD 6870's crossfire, and didn't have any issues. I didn't own them long enough to find out any true problems with crossfire, they do scale rather well for performance. Before that I've always been a single card solution type of person, to me it's just less hassel.

Only reason I switched back to one single card solution is I went 3D vision for gaming and 3D movies and went Nvidia.

So again, advice would be for "best bang for your buck" is buy another 6850, since that was what you asked for in your post. Again your half way there.

Hi,

Read thru this thread and there is logic on both sides.

Cf has evolved over the last few years- hardware and software wise.
Have played with the GPU's since the Pci and Agp days,shhhess,redface.gif Just dated myself.

Big single card means less heat,less possible driver issues, cheaper wc costs
if going that way.

Started with single 5770 in my rig and only reason went CF was to keep up
with the newer games.
Took about a month to get cards to play well togeather, newer gadgets and info helped alot.
Now kinda of hate to upgrade as do everything very well.

Big single now and CF when it starts to fall behind.wink.gif
Possible cost of a single big card now you probably get back when you get
the 2nd card later on.

JMHO

Later:D

The 6850's and 6870's generally (sic.) scale very nicely. Even still if I were you and had the cash I'd get a 580, or wait until 28nm GPUs start coming out.

Thanks for the info guys smile.gif

My PSU is pretty bad, so I'd be upgrading it regardless of what graphics upgrades I get. So PSU factors aren't really a issue for me as I'd be upgrading it anyway.

I'll be gaming on a single 1920x1080 monitor, occasionally two of them, but not very often.

I'm in no huge rush to upgrade (my card is doing pretty well for the games I play), so waiting for newer cards is definitely an option for me. Will there be a marked performance increase in the next series? Cause I've found dx11 support on this card especially quite bad, so maybe waiting for a newer card which can handle dx11 is a good idea?

Again, thanks for all the info, good food for thought smile.gif
