I actually doubt that will happen soon. CPU cores are increasing faster than GPU cores currently. And current GPU designs are massive, you really can't do multi-core GPU's unless the entire design paradigm changes immensely (although current GPU designs do use multiple execution units) I expect to see increased reliance on GPU's for certain calculations (anything 3D, UI acceleration) but better handling of multi-core CPU's will net a bigger improvement much sooner. -- M.
