Intel Core 2 Quad Q9300 - Core 2 Quad Yorkfield Quad-Core 2.5 GHz LGA 775 95W Processor - EU80580PJ0606M - OEM

Pros: Runs as expected. I am not ambitious enough to overclock this to its peek performance level, I set the bus speed at a modest increase, @ 450MHz and am happy enough with this speed, (3.38GHz.) I am upgrading from a single core obviously there is no comparison. Encoding videos in standard definition H.264 codec dropped from ~5 hours to just under 30 minutes.

Cons: There is always room for improvement, but I have no complaints.

Overall Review: I do a lot of research before I make any major purchase, there are of coarse better CPUs on the market, but they cost more, and there are certainly less expensive ones, but they aren't as good.... Duh. You should do your own research, but unless you are ultra-conservative with money, you will likely end up choosing one of the Yorkfields.

Pros: The CPU was priced low and came with free and lightning fast shippping, Great Customer support

Cons: The CPU didn't work, PC always crashed while booting. Replaced it with my Q6600 and PC works fine. CPU was returned for RMA witha free shipping label - Big thanks to Neweggs excellent Customer Service

Overall Review: Fast RMA - with refund - bad that the Q9300 didn't work. questionable Qualiy control on Intel side..
