Tom’s Guide Daily has a story detailing pricing information for AMD’s upcoming X4 Phenom quad-core, desktop processor. They also talk about pricing for Intel’s soon to debut quad-core Penryn line (which is supposed to launch on Nov 12, 2007)
According to sources, Intel will not deviate from the pricing strategy that has been in place since the introduction of the Core architecture in July of last year. Its high-end enthusiast chip (QX9650, 3.0 GHz, 12 MB L2 cache) will launch at $999, the high-end mainstream-processor (in this case the Q9550, 2.83 GHz, 12 MB L2 cache) at $530 and the mainstream versions below at $316 (Q9450, 2.66 GHz, 12 MB L2 cache) and $266 (Q9300, 2.50 GHz, 6 MB L2 cache).
It looks like the sweet spot (if you are a hardware enthusiast, willing to do some over-clocking), is the Q9450, at $316, with 12MB of L2 cache. You should be able to easily overclock that CPU to the 3.6GHz range on stock air-cooling. That would be an ideal CPU for games like World in Conflict and Supreme Commander.
