Console video games post continued sales declines in October; lackluster titles a key factor

As the launch date for Microsoft's Xbox 360 approaches, an NPD Funworld analyst tells TG Daily that retail sales for console games in the US continues its downward trend: down 24 percent in October versus the same month in 2004. But what could save the year yet - in fact, what could make it a record - is the resilience of a little something called generosity . Read more

I've heard there is a code written on the chip casing that contains this info. I've also heard you can check it by finding the chip's data sheet on the manufacturer's website. Well, I went to the Intel site and they have a graph depicting the temperature at many different wattages. The highest wattage listed for my chip (Q9550) is 90watts and the temp there is about 70C.
Is this the max temp I should approach if overclocking? Are there any safe parameters for heat or is it largely dependent on which chip is being used?

Each processor has a rating, in which you should not go over for temperature. This temperature is not for the core temperatures however, as they can go much higher before being damaged. I have a q9450, which is very similar to yours, and it is rated for 71 degrees C.

I just went to the intel website and searched for q9550, and got this:

Thermal Specification: 71.4°C

71.4C is for the "CPU" temperature, not the cores, which have a max temperature in the range of 95-100C.
