Well. SLI is the multi graphic card mode for NVIDIA cards. Cross fire is the same concept for AMD cards.
You can use 2 GPUs of the same model and speed to pair with each other and double the performance of the Graphic Processors. But this needs a Motherboard that supports 2 way, 3 way or even 4 way SLI or crossfire option.
The power requirement in multi GPU setup would double because both cards would be using its own power requirement. So if you have a GPU that uses 250Watts and if you pair it with another one of the same model, the effective power requirement for the GPU alone would be 500Watts. And this plus the other components of the computer would take around 650-750 watts on total. So a PSU with at least 850 Watts would be preferred for a safe margin.
At this stage, if you are planning to go for high resolution high FPS gaming, GTX970 SLI would be a good starting point. Going even higher will only increase the capability for high resolution high FPS gaming but you need to have suitable high end monitors in multy monitor setup to get full advantage of this.
For now if you are planning for multi GPU option, go with SLI with 2x GTX970s or Crossfire with 2X R9 280s.

If you're looking for a graphics card(s) then I wouldn't go SLI, the extra power usage isn't worth it when their are single cards offering similar performance, providing you not speaking of SLI top end cards.
