What i was trying to get as is Netburst at 3GHz would be competitive today without K8-arch in the market, and Intel had no need to replace it anytime soon.
Complete and utter nonsense. The perpetual need to keep users interested in upgrading their systems on a regular basis is far more important to Intel's total sales than swapping a few points of market share back and forth with AMD. Product stagnation is tantamount to sales stagnation in the wealthy PC markets.
