the GPU can't be confused with a CPU
the CPU is needed like it or not, Nvidia is only trying to make it possible to use the GPU s power to help out the CPU on CPU intensive apps NOT replace it
Also Nvidia probley won't get one to make x86 CPUs anyway...as it will be expensive they might as well do what they are doing now
And just imagine how hot that NV x86 CPU run & of course have loads of incompatible extensions that NV would prod developers to use just like PhysX.
