    That is probably pushing it a bit. I think you should just put the money toward a more powerful single GPU like a 680. How much will you spend on the 660s? You may need a upgraded PSU also. Any thoughts Blkfx1 and hellokitty[hk] about the PSU?

    In my country is much cheaper to buy gtx 660 in SLI than gtx 680,my psu have 12v1 24A and 12v2 24A so total 576w on two rails

    The GTX 660 only needs one 6 pin connector so you PSU is fine in terms of connections.

    The MSI TFIII isn't the best cooler though, check out the Asus DCUII or Gigabyte Windforce solutions.

    The TF is pretty good, the new dust cleaning feature is garbage though lol.

    I can choose gtx 660 in SLI or gtx 770 lightning,but my psu have one 6pin and 6+2 pin and for lightning I need 2x8 pin so I must use 6 to 8 pin adapter,is it safe to use that adapter also I want to oc a little bit?

    Dont waste your money on that Lightning garbage. 1) MSI products havent been good from my experience. 2) The TF cooler is gimmicky and cheap. 3) It is overpriced. Get this instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130921. The EVGA 770 I recommended requires a 600W PSU: http://www.evga.com/Products/Product.aspx?pn=02G-P4-2773-KR.
