The Core i7 950 would run at a steady 3.06GHz, roughly 130MHz faster than its 940 predecessor. The product would be at $562 in quantities of 1000.
The Core i7 Extreme 975 that we mentioned, will run at 3.33GHz, roughly 133MHz faster than its 965 Extreme predecessor, and will be priced again at $999 in quantities of 1000. We are not sure of the Core i7 940 & 965 will go End Of Life (EOL), we very much doubt that to be honest.
Of course you can also purchase a Core i7 920 and overclock it to the new speeds, relatively easy.
