Yes of course. But why is there a need for that ?

It is always best to pair identical spec'd cards, and the Lightning is a 2gb memory card and the Classy is a 4gb card, the clocks are close enough so you'll just have to see what happens, I would imagine you'll loose the extra 2gb of memory in the translation as they'll be clocked to matching equality more than likely.

The most important thing is making sure you have the power supply to handle an SLI setup, I'd recommend a single 12v rail power supply in the 800W + minimum range, and preferably closer to 1000W.

Good Luck to You!
