Question about SLI of Crossfire with Asus z87 pro moterboard

[Louis_liu]

I'm planning to build a computer use Asus z87 pro motherboard, I will use i7 4770k and two GTX670 or ATI7970. If i use a 860W power supply, is this motherboard good enough for SLI or Crossfire?
thank you

Absolutely! But will not tri-SLI any good as it has only 2 x PCIe 3.0 slots, which is fine, it is a great board.

I will use a 860W power supply(SeaSonic Platinum Platinum-860) in the pc. Does it strong enough to SLI two GTX 770?

Yes, that is plenty, if driving 3 screens the 4GB boards would be nicer....

I went the cheap route and crossfired two HD7770s as for now i only have a single 22-inch monitor.

They work brilliant.

When I can afford a triple 28-inch 3D monitor set-up in 4K when they are out in 2014>..... and two magic cards from 2014>, I will be in dreamland.
