i currently have the BFG 9800 GTX. Should I get a motherboard, say 780i, to support this or should I opt for an INTEL chipset and get ONE videocard, say GeFroce 260, that is running at 1 GB. What are advantages/disadvantages of SLI???

Welcome to the forums!
Go for i7 if you can. Supports both Crossfire and SLI.
That card is still good. It should work with both Intel and Nvidia motherboards. Not sure what you have now.
