Solved Need new mobo for Xfire 5850? gigabyte890gx Tags: Radeon Support Motherboards PCI Express Graphics Last response: May 1, 2010 4:40 PM in Graphics & Displays Share tuesday0180 May 1, 2010 2:53:28 PM My motherboard has two PCI-E slots at 16x or 8x8x Is the 8x 8x enough to support crossfiring 5850's? Or should I just go for a 5870? Reason I want to xfire 5850 is I want to spend around $300 right now and be able to upgrade with xfire in the future.
