"QC will not be an issue just like 64 bits is not an issue now. "
Not sure what you are trying to say here. 64 bits is, and has been, an issue in servers for a while. QC will be an issue as soon as one or the other company manages to ship one. There is always a need for more processing power, and given the heavily multi-threaded environment for servers, it will get used.
No need to wait around for Intel.
