I currently own an i7-860 and im thinking of getting another gtx 470 SC edition card to make it SLI, I reasearched and discovered that my CPU doesnt support multi-GPU or something like that, most of the times I saw it being VSed with the i7 920... does this mean I cant SLI my system? should I overclock it? if so, what cooling system should i buy?

Your i7-860 is not limited to a single video card. You could do SLI with a GTX 470.
It is capable of handling as many as you can install on your motherboard, providing you have enough power.
You forgot to mention what motherboard and power supply you're working with.

Also - just out of curiosity - can you link the research you found saying the i7-860 doesn't support multi-GPU (Crossfire or SLI) systems?

I have a Intel DP55KG Extreme Series Desktop Motherboard which supports SLI but only has one 16x port, the SLI would be dual 8x then :S, is that a problem? is there a major difference with dual 16x?
I have a Corsair certified 850TX series

That is more like an opinion than research.
You have a good motherboard and PSU. DP55KG Extreme Series P55 Motherboard review Your motherboard and PSU will easily handle 2x 470 in SLI
It's normal for a P55 motherboard to support SLI or Crossfire @ x8-x8 vs a X58 motherboard that will do x16-x16.
There is a slight fall off in x8-x8 vs x16-x16 performance but it shouldn't be a major concern to you.
