what does "running in cross fire mode up" mean in:?

Question

Hower, rumors are circulating that pet the latest dual ATIX1900 GPUs running in cross fire mode up near the one teraflops range, so it would be safe bet that a 4 to 5 times speed increase shown above should be viewed as a consecutive estimate.

PS.: GPU=graphics processing unit

Answer 1

ATI's "Cross Fire" mode lets two GPUs in the same machine work together to render an image. According to that statement, rumors are going around saying you can run two of ATI's new GPU in a "Cross Fire" configuration and get around a teraflop (1 billion floating point operations per second) of performance.
