Key Product Insights
* Unique Architecture: Unlike standard consumer chips of its time (LGA 775), the QX9775 uses the LGA 771 socket, typically reserved for server-grade Xeons IntelGotodirect.
* Extreme Performance (2008): It was the first desktop processor to push the 1600 MHz Front Side Bus (FSB) and featured a massive 12MB L2 cache at a 3.20 GHz clock speed IntelGotodirect.
* High Power Requirements: With a 150W TDP, it requires specialized high-end cooling and motherboards, specifically the Intel 5400 chipset (Skulltrail) PugetsystemsTomshardware.
Current Market Trends & Value
* Price Appreciation: While it launched at $1,499, it currently maintains a surprisingly high resale value of $250–$300 on secondary and specialty markets TechnicalGotodirect.
* Collector "Trophy" Status: The QX9775 is increasingly treated as a "trophy" component. Its scarcity compared to the more common QX9770 makes it a centerpiece for "period-correct" ultimate gaming builds from the late 2000s AlibabaQuora.
* Supply Scarcity: Modern B2B platforms like Alibaba and Global Sources no longer carry new stock; availability is limited to refurbished units from specialized computer component suppliers .
