i need help with graphic card

[zuti]

I want to buy new graphic card and i have already decided which one will be, it s xfx 6850, but on anand bench i saw two kinds of 6850 graphic cards one is regular 6850 and other one is 6850 cf, my question is what that mean (cf) and what is difference between them. thanx

cf stands for "Crossfire" and it's a term used to imply using more than one GPU in one system. They work together to give you better performance (although they don't scale 100% and are known to cause a few more problems in games). I'll let others with Crossfire elaborate more.

This system has 2 GPUs in Crossfire (cf). You can clearly see the Crossfire bridge between the two. This allows data to transfer between them/communicate.
