No one knows what is going to happen at 1ghz yet. One thing that has been seen is 'atom migration' where at such frequencies, material on the chip physically moves around. The effect on ICs is unknown at present. 2. HAM radio folks know (as do those having had a physics course that covers electricity and magnetism) that at 1ghz frequencies, electrical properties change significantly (ie check out coax cable used for normal RF frequencies rather than the waveguides used for microwave frequencies). What happens inside at these frequencies is going to be interesting to find out. Ie yes it _can_ be done, but _do_ we really want to do it? :) That was one of many issues that prevented Seymour Cray from producing a 1ghz machine before his death. 1ghz is _tough_. And 2 ghz is _really tough_.
