Well, no crossfire for me =(

[NotAnalGrap]

I spent a good few hours last night trying to get crossfire to work on my computer.
After many hours of pain, I finally figured out that my second PCIe port seems to be dead. So until I have time to replace the motherboard, no crossfire. Perhaps I can save up some dough in time for BF4 - but then I'll have to do a clean install - which will be a pain.

Anyone one else running crossfire and seeing it worth it?

That sucks. Saves you the pain of not working when its supposed to work anyhow amiright? jk

What cards? The lower down the rung the cards are the worse they perform in relation to stutter and putting out frames at a smooth rate instead of spitting out a couple at a time. A pair of 7970's can put out a great experience while a pair of 7850's might have a great frame rate in comparison to a single 7970 but it not be quite a smooth as desired.

Multi card is a must for multi monitor, often a requirement. Simplicity is often most reliable and 2 cheap cards are usually a bad idea. Other questions can come into play such as is your monitor 120hz? If the base card puts your averages 60 or over your not gonna get much benefit from a second card.

I have 2 7950's. I've been running just one for quite awhile and had the other in a separate machine. 7950 performs great, and I've got the extra card and the power - so why not, right?

Still running a 60hz monitor. I haven't measured my FPS in BF3, but I did get some frame rate issues in Bioshock Infinite on Ultra settings with just the one card.

7950's should be good. If everything is smooth there is nothing wrong with achieving that magic goal of having a 60 fps minimum in some of your games.

When compatibility isn't an issue the problem is inconsistant frame times. If a card averages 60 fps then on average every 16.5 milliseconds it spits out a frame. Though each frame time actually varies. There is an issue known as micro stutter and its not always visible to the user and if its not most choose not to worry about it. It varies by manufacturer, card, driver.

But basically dual card has a tendency to spit out 2 frames really fast and then have a large delay before spitting out 2 more frames. If that delay were to exceed 41 milliseconds anyone in this world would notice the screen freeze as fluid motion is broken. Thats pretty rare. The relevant issue is if the delay were say 22 milliseconds then 2 cards getting 60 fps looks no different than 1 card getting 45 fps. Best case scenario, worst case your annoyed to no end and florescent light bulb flicker (not broken ones) probably also drives you nuts.

But then there is that occasional OMG i took one card out and everythings better moment. You have the equipment so not much wrong with trying except of course your current issue.

That's why I went with one nice card instead of doing crossfire. The inconsistency, the flickering, and thus stuttering drove me nuts. I'm quite happy with what I have now.

I had 2 6870's in crossfire..they fucking sucked donkey ballz for bf3. stuttered like a bitch.
I gave them away and got a 6970...way better. I doubt I would ever go multi gpu ever again.

Have a lot of experience sucking donkey ballz do you? Is that what passes for entertainment in the Great White North?
