I'm only guessing, but the i7-980X is reputedly aimed to cost around $ 999 and is in a different category than the i7-920 and i7-950. The i7-975X is the leading chip at this moment and will probably drop in price. Whether that means the lower end chips will also drop in price, I don't know. It could be that the gap in the Bloomfield range will narrow. Up to now it is pure speculation, but I do expect the i7-980X to be introduced before fool's-day. Market availability is another matter, but somewhere in the next four weeks I would expect the announcement to occur, with availability shortly after that, say around May.
Since your computer is such a " BEAST "
Do you think you will go the 6 core route when it comes out or wait since yours is running at the top of the PPBM tests ?
I'll wait a bit, because for me the performance difference does not directly justify the difference in price.
