Question  will this work? by erne

will this work with #44709??

Answer by stewartz on Wednesday, July 27, 2011
That should be fine.

Comment by Juno

the AMD website states that the 870 chipset doesn't have crossfire enabled, what are the extra PCIe slots intended for?

Response by andrewn
Multiple graphics cards? You can run multiple graphics cards in non crossfire/SLI mode. Or alternatively for other non-graphics PCI-E cards. And SLI/Crossfire can sometimes be made to work even when they don't have 'official' support.
