I'm just more familiar with SLi. I wouldn't mind trying xFire but I'm not a big fan of the whole master card business.
 
To be honest, both are really good. The only problem with xFire is the master card/dongle business, but that is now being fixed with the built in xFire (see the x1950 pro). Overall, xFire is a little behind SLI, so I think that SLI is better, but with the release of the x2000 series from ATI, that gap between the technologies will close alot.
 
SLi is a more mature technology that scales extremely well in most games. Crossfire is good, but most people just don't have the conifidence in it that SLi has. Plus it has great OpenGL performance. SLi for me.



 
Crossfire for me - before the 8800 came out two X1900s/X1950s were the best performance available, and as of Catalyst 6.11 you don't need a master card any more.
 
Sli, supports more games, you can mix and match, it is more user friendly, and... NO DONGLE! Lawl:p Not to mention the individual game profiles, and the different rendering modes. Also some what more mature.

not to start a war here, but anyone no matter how big a !!!!!! they are would have to say SLI if they were honest with themselves....CF just hasn't panned out

out of 12,617 steam users with multi GPu systems polled with SLI touting 12,118 compared to 493 CF users seems to tell an unbiased story, i was going to add that tidbit but empty beat me to it
 
after working with both, i like SLI better. I did not care for the master card/ dongle BS ATI had going on.

I think i like nVidia cards a lot better, they run cooler and quieter, and i think for what i play i get better performance.
 
Nice to see more results coming in aaaannnndddd SLi has the lead(lol) 75% Ali and 25% for Crossfire, im pretty sure we have alot more people on this fourm board who can post...

I'd have to agree with that. It's very hard to make a strong case for the superiority of CF. Although you'll have people voting based on what company they like or what card they have - from an objective standpoint SLI still has to come out on top. That might change with R600 though. Nvidia really hasn't done anything special with SLI for G80.
 
I've had both, and I just prefer the software setup of SLI better than Crossfire. The Catalyst Control Panel interface blows.

No. The 7950GX2's were slightly faster than Crossfire X1950XTX's. Granted, it really does depend on the games you were comparing the two in. Even with Catalyst 6.11 you still need the dongle for higher end Crossfire cards and the new X1950Pro requires both bridges to function.
 
SLI is great when it works. Unfortunately the numerous bugs in both versions of nvidia's control panel mean I'm usually disabling & re-enabling SLI at least every day or two (to get it to use the correct profiles) and reinstalling the drivers every month or so when the profiles get fucked up and decide to get stuck on something stupid like 2x SLI AA, no matter what I configure.
 
My twin x1950 pro's work great in xfire. No problems whatsoever. Running WoW TBC at 6x AA Temporal set to quality, 16x AF HQ @ 1920 x 1200. I average between 25 and 60 fps. And it has been stated that R600 will employ the same setup as 1950pro's for interconnects. At least that is the world. So yes xfire does work as it should i am completely happy.
 
I'll have to agree with the majority here. SLi has just had more time to mature. Granted, it's still going through some growing pains. Overall it is generally stable.

I did have some quirky problems with SLi (but that was mostly because of WoW and not SLi's fault). But every 2 months or so I found myself reloading drivers.

I've never had issues like this. I've been using SLI since the Geforce 6 series came out in PCI-Express. Basically, since the beginning weeks of SLI being available.

Yes they do. I used a pair of X1950Pro's with my Gigabyte GA-P965 DQ6 2.0 review board and they did work flawlessly. Hardware wise, it's setup just like SLI.

Generally it works pretty well. There are games it doesn't work with right away, and it really requires that you setup your own profiles to take advantage of those games. It's not hard, but can be time consuming. WoW seems to have always hated SLI, and as far as drivers go, I typically update to new ones when they come out. If the newer drivers suck, I go back a version. So I reload drivers quite often too, but never because of a malfunction.
 
XF on dual x1950pros for me. I hate the Nvidia game profile crap. However, I also hate ATI drivers, and CCC. I'd rather deal with one crappy central location (CCC) than manage a different profile for each game.

You don't have to manage multiple game profiles. You can use a global profile if you wish.
