Crossfire Questions

post #1 of 2
Thread Starter 
how does Crossfire actually help with games? does it boost frame rates at a given res, thus allowing you to add more eye candy like AA and so on?

from what i have gathered it does, but at a cost of frame rate spikes (as in min frame rate can often drop) and doesn't always work nicely with drivers. Is it true?

It's two cards working to perform one task. It won't be twice as fast (scaling isn't perfect), but putting a 2nd card in will increase performance (depending on the game) by roughly 50%.
