I have a
Asrock H77M motherboard and a 7870 XT Tahiti-based video card.
My motherboard supports CrossFireX, so I was going to buy a second Tahiti-based video card.
The website for my motherboard states:
- 1 x PCI Express 3.0 x16 slot (PCIE1: x16 mode)
- 1 x PCI Express 2.0 x16 slot (PCIE2: x4 mode)
- 2 x PCI slots
- Supports AMD Quad CrossFireX™ and CrossFireX™
Since the second PCI Express slot is slower than the first slow, will this slow down the second card?
Or - is my motherboard fine to use CrossFireX?
