Hi guys. Right now I'm planning to get an i5 4690K and one GTX 970.

Apparently, 550W or so is enough for this, according to some of the people here.

However, I plan to SLI two GTX 970s in the future, when a single GTX 970 can't handle the games anymore at high settings.

Should I get a 550W PSU now, then get an 850W later?

Or would I be able to save by getting the 850W now?
