Crossfire Myths, i have a question... or two..

post #1 of 41
Thread Starter 
So, i am about to fork out a few grand for a laptop that uses Two HD 6970m's I have always been an nvidia sli user on the desktop, i run two GTX 460s, I started using SLi when the 9600GT came out, i am aware of all the multi-GPU Drama one can get in, but in general i've never had a problem.


I've heard people however complaining that Crossfire flickers alot, can someone tell me if thats true?

I've heard that Crossfire profiles have been a ***** to setup, could i get some more info please?

and lastly, What would the 6970m Be equal to against a desktop card, i know Laptop cards are watered down desktop cards, but if it were pit against a desktop card, where would it be at?


I am sure i have more questions, these are only what i remember, thank you for having the patience to answer.

My crossfire set up doesn't flicker at all...

headscratch.gif I can't say much on Crossfire profiles because I never set one up, I just enabled Crossfire and enjoyed the prettiness 8)

6970m is the mobile version of the 6970.

It doesn't perform nearly as good as a 6970.

Don't use Windows Vista for gaming. In some cases it can double the system requirements needed to play games. Windows 7 is far better.

Basically, as soon as you install Catalyst Control Center (ATI's Video Drivers & Control Panel thing) You can just run CCC as a program, or right click the icon on your task bar, and go to Crossfire settings, and just check "Enable Crossfire" then reboot your computer and you're good to go.

Vista is only on my desktop as dualboot so mass effect runs without giving me QQ on DRM, won't do it for win 7, Thats why i also listed it on the laptop, only for that reason however. Both of those systems, are prebuilt, would you have any suggestions for them? any changes i should make?

As an alienware crossfire laptop user, I'd do it again in a heartbeat.

The M18x is the only laptop available with dual 6970s and a sandy bridge processor, so it's kinda your only option, albeit a great one.

Over the last 2 years i've used crossfire, first a desktop with dual 5770s + eyefinity and now this laptop, I don't normally experience microstutter. Brink is a great example of the worst experience I have run into with crossfire.

Brink is released, and there's no CAP for it and it is heinously optimized for ATI cards... 15-25fps

a week and a half later, drivers are released... solid 30fps but still not CAP

a week and a half after that, the CAP is released and crossfire is working, I now get solid 60fps at default resolution/settings

5 minutes after launching Brink with working drivers and CAP, I realize it's a piece of trash and thank ATI for keeping me away from it for so long.

Everything works, eventually. It's an annoyance at worst. Again, coming from someone running crossfire for about 2 years now, I'll do it again next time I upgrade.

I have another question if i may, unrelated, This is for desktop Crossfire, i am about to pick up one of the new 990FX boards since the one in my sig is dead, I use Nvidia 2d surround but one of my GTX 460s is also dying(Dead fan controller, won't go above 50% fan) I was thinking of putting together an ATI eyefinity setup, but the looks of all these DP to XX converters confuse the hell out of me, My monitors only have DVI on them, is it still doable?


Admittadly, i am a Reformed Intel fangirl, i had heard nothing but bad about AMD and ATI for years, Then i went from a core 2 quad Q6600 to an X6 1090T and holy hell things were so much smoother, specialy in wow, i went from 15-30 fps to flat 60 with my first SLI setup. So now i am here to quench all the ATI myths i've heard about and hopefully join camp red aswell
