I think AMD have already lost to many sales now. They used to be widely used for people looking for good cpus at cheap prices. But now they have lost for so long to the C2D i dont think they will retain their title. I had pritty much forgotten about AMD. Dont get me wrong, the price cuts are good bargins. But when someone asks what CPU should you get. Do you say, "Get the AMD because its a good deal" or "Get the Intel because they over clock well, a decently prices and are more powerful."
If someone asked me what CPU to get, id point them at the C2D every time now. Before i would have said AMD. No body really goes for single cores any more it seems and that was where AMD seemed to win in my view. The duel core on the CD2 is not much more and overclocks like a beast.
I cant see many people buying AMD's over Intel any more unless they bring out a really good duel /quad core at a cheaper price then Intel. Even if its better, if its the same price a lot of people will probly just go for the intel because not everyone knows about whats best when it comes down to it. The majority will follow the crowd, and the crowd is at Intel.
