can i SLi with this motherboard?

The Z68 chipset can support SLI, so it's theoretically possible. The drivers just don't allow it as the board isn't licensed.

You could try HyperSLI.

But the second PCIe slot is only a x4, so you would lose some performance (maybe up to 20%, depending on the games and which cards you use).

Compared to what? Any performance loss will be from using a x4 slot, not from using HyperSLI. That P45 board x8 slots. There would be little (if any) loss from using these.

so i can only get 50% power from the card if i attached a second card for a hyper SLI?

In x8 x8 no, but with x16 x4 you will notice.

50%? Where did that come from?

Actually the figure I quoted was remembered from a test I saw comparing the performance of cards in x16 slots with those in x8 and x4 slots. But I couldn't remember the details clearly. I've checked again and the performance losses were only at very high resolutions. Up to HD resolution, they found no real difference.

However, I have tried this myself and have to disagree with them. I did see measurable losses in some games at x8/x8. They were not great (the worst I saw was about 4%) and some games showed no loss at all. I could not test at x4, as I have no x4 slots, but the effect is likely to be worse. But you should still be OK, I reckon. At least one of your cards would be running at x16.

Even if one card was running 10% below par, the overall effect in SLI would probably only be about half that. A 5% loss in a game that might run at 65fps would only be about 3fps.
