performance difference between dual HD 5770's and a single HD 5870
in the 2010 8-core mac pro what is the performance difference between dual HD 5770's and a single HD 5870 when doing things such as 3D rendering or gaming on the 27" cinema display?

This is really going to depend greatly on the system you have. Final Cut Studio can utilize multiple graphics cards for rendering. Most 3D modeling software is not optimized in Mac OS X for this function. The best practice of multiple video cards on a Mac Pro is for powering multiple monitors. Software is not designed to support this like on Linux or Windows and without Crossover or SLI technology, the hardware benefits of linking are not available. With one monitor, I recommend the 5870. WIth more than one monitor, you should really ask on forums devoted to the software you are using.

The dual 5770's let you attach more screens but doesn't really increase your performance much. The 5870 is pretty much twice the performance, wider memory path, faster clock, etc... It's just faster... There are now cards that are apple certified that are much faster than the 5870 too...
