GTX 580 SLI vs GTX 590

[John544]

Is it advisable to go with GTX 580 SLI or should I go with GTX 590? I heard there are performance issues with GTX 590 quad SLI.

GTX 590 is basically 2 GTX 580 downclocked.
So overall 2 580's are faster.And yes,there are performance issues with quad-SLI due to "not-so great" driver support

GTX 590 = 2 X GTX 580s underclocked

GTX 580 SLI is faster than a single GTX 590.
GTX 590 in Quad SLI does have performance issues.
