SLI reference or non-reference 780's

[shadow85]

I have been waiting for a while for some factory OC'd non-reference GTX 780 cards to come in stock, so I can SLI them. But it's taking a while and I might be waiting months yet till I can get some good OC'd non-reference 780's.

I was wondering is it OK to SLI non-reference cards, as they will blow more hot air on each other, or should I stick with reference models for SLI?

If your spending $1300 on graphics cards, then I assume you would have a case that can deal with that heat output and can supply fresh air to them. Go non-reference IMO.
Also, non-reference cards in stock.
