Mac Pro 2.0 Intel Quad Processor Upgrade Question??

[digitaldrip]

Hello Everyone,

I recently got a bargain on a 1st Generation Mac Pro 2.0 Intel Quad. I'm interested in upgrading the processor to the Quad 2.66. Will either of these processors on newegg suffice:

Intel Core 2 Quad Q8400 Yorkfield 2.66GHz LGA 775 95W Quad-Core Processor Model BX80580Q8400 - Retail

Intel Core2 Quad Q9400 2.66GHz LGA 775 95W Quad-Core Processor Model BX80580Q9400 - Retail

Thank you for your time!!!

No. You can only use Xeon 5100 (dual core) and 5300 (quad core) series processors. Your Mac Pro has two dual core processors.

The processors also need to be Socket 771.
