Is there a PCI-E card that is SLI capable

BUT

You don't have a second PCI-E slot. Huh?

You need a motherboard with 2 PCI-E slots.

* If you did have a twin PCI-E motherboard and you bought another 8800GTX, I would be advising you to install a much bigger Power Supply before turning the system on.

Chances are your existing power supply would die and might even take the motherboard with it, due to the increased current required for the second 8800GTX.

nonono lol i dont have a second PCI-E x16 slot, but i have plenty of PCI-E slots

The relatively slow bus speed of PCI-E would defeat the purpose of SLi. You would be running two cards that were both heavily throttled-back.

That is if you could get them to fit the slot, which I seriously doubt.
