I recently bought my new computer. It has an XFX R9 280X Black Edition. In the future, can I run crossfire with this card. My motherboard is a Gigabyte H87-D3H, which has "1 x PCI Express x16 slot, running at x16 (PCIEX16)" and "1 x PCI Express x16 slot, runnig at x4 (PCIEX4)" What does this mean? Can I crossfire in the future?
Also, if I do crossfire, do the cards need to be the same brand (e.g XFX and XFX) or can they be two different brands (XFX and Gigabyte)?
