is a i5 processor good enough for 3 x 660 sli ?

Solution
Why would you want Trifire GTX660? They would scale horribly and not a single Z77/Z87 motherboard support 8x8x8, one would run in x4 PCI-e mode, which is gonna slow the other 2 cards down VERY hard.

No reason to have 3 of them. 2 GTX760s are better and around the same price.
