RISC vs CISC is almost a non-issue as far as performance goes. The advantage RISC offers is that it simplifies the design process, and sometimes allows you do the same job with fewer transistors or less power. X86 designers long ago learned to compensate for the limitations their ISA places on them, so this leaves the only advantage as R&D costs, plus a little bit of die size. The economies of scale enjoyed by the X86 processors more then compensates for this.
