The Core 2 Quad Q9450 works at 2.66GHz, has 12MB memory and works with FSB1333MHz. It is packed in socket LGA775 and it will sell for $319. I guess that this one will be very popular as it has the whole 12MB cache and it costs only $49 more than $270 Q9300.
The fastest Core 2 Quad is Q9550 clocked at 2.83GHz with total 12MB of cache, FSB 1333 and LGA775 support. This one will sell for $527 and it will take the place of Q6700 that served for so much time.
The remaining QX9650 and QX9770 are branded as Core 2 Extreme, so we won’t talk much about them apart that QX9650 costs $970 while the QX9770 will cost $1390 and will be the fastest Core 2 Quad socket 775 planned for this release.
