Any Crossfire set-up which is cheaper with better performance than a single card?

post #1 of 6
Thread Starter 
This has probably been posted many times, but being new to the forums, I haven't seen anything about it.

For example lets say Card 1 costs $500 and Card 2 is $200. Card 2 in Crossfire X costs $400 and has better performance than Card 1.

Do any set-ups like this exist?

two 6870's are about the price of a 6970 and are faster.

I think the Idea that I like about crossfire is I can buy power on time.. Like one now one later and then another one when the price drops to the basement.

That is pretty much my theory about xfire or sli... future upgradability.

^^As long as you don't buy dead end cards upfront, like the cards with only one crossfire/sli bridge.

You could get 3 6950s for the price of 1 6990 and obviously be faster, as well as being faster than sli 580s.

Uh.. no. Looks like about $420 to get a foot in the door with 2 6870s, and only about 340 to get one 6970.

The 6870s do perform better though.

On the Nvidia side, the 460s and 560s have been outperforming the flagships for less cost since last summer. I'm sure there are comparable Crossfire setups.

TSM: There's nothing "dead end" about cards with only one connector. 2 way SLI/Crossfire is very practical, while 3-way is less so.
