As I said, all you need to do is look at the specifications page of the motherboard:
Expansion / Connectivity
Slots - 1 x PCI Express 3.0 x16 Slot (PCIE2: x16 mode)
- 1 x PCI Express 2.0 x16 Slot (PCIE4: x4 mode)
- 2 x PCI Express 2.0 x1 Slots
- 3 x PCI Slots
- Supports AMD Quad CrossFireX™ and CrossFireX™
Based on the above the ASRock Fatal1ty H97 Performance board would not be able to use two NVidia Geforce cards in an SLI configuration (but it could use two AMD Radeon cards in a CrossfireX configuration).
Here is a list of motherboards I would consider for your processor and a future SLI configuration. Since you are looking to SLI, I would probably stay away from any Micro-ATX motherboards. Beyond that, it really depends on your budget.
