Can any one say what will happen when you try to sli with a H77 motherboard . Though it is crossfire certified . I m particularly interested in this motherboard for corei5 3450 - processor . The motherboard is MSI ZH77A-G41. It shall be mainly used for gtx 660ti sli . Though asrock pro 3 is a z77 motherboard and it has one pcie running at x4. Due to very tight budget I can't afford it . So any suggestions shall be appreciated.
