As most people may or may not know, when you buy your shiny new computer, it's the best thing you've ever used. Then about three years down the line it begins to slow down and takes an age to do anything. I had reached that three year point and decided i needed a new cpu to give my pc that little bit more ummph, i didn't want to replace the whole system just as few parts as possible. I new most of the system was still pretty up to date, apart from the cpu and a bit more memory. After checking out my mother board on the web and discovering it had a 775 slot fot the cpu, i went about researching the best cpu there was for that slot. Then i compared cpu's just below the best one for price and performance, the Q9550 2.83GHz gave good performance for the very reasonable price, the reviews were good, they are a solid performer and since the intorduction of the Intel I series pc's there a some bargins cpu's to be had as the gaming community update to the latest technology and sell their current systems. The cpu is very straight forward to fit, quiet and efficient and performs exactly as reviews suggested, it's been in my system for a few months now and hasn't missed a beat, more than happy with it and it has given me the extra power i needed to return my machine to it's former speeds.Read full review
After much experimentation on my old Gigabyte EP35 DS4 motherboard I found the best settings were fsb 425 with the tiniest bump in voltage-0.025v in fact the smallest increase the bios permitted. With the memory divider set to 2-it's speed was 800mhz. This gives 3.4Ghz and just 55 degrees C under load with a cheap freezer 7 pro cooler, it is rock solid for stability, and on various benchmarks is faster than standard elderly i5s. It would go to 3.5Ghz but my memory wouldn't tolerate it without increasing its voltage. Definitely found 3.4 was the sweet spot. Of course your mileage will vary with different parts and setups. BTW mine cost me just £20.

Fantastic price and still a pretty capable processor (even though it’s ancient in pc terms) obviously some missing extensions so some demanding modern software may have issues, but it is fine for browsing/office and fairly good at gaming so long as you choose the right titles. LinusTechTips “$69 Gaming PC” challenge was based on one of these, so check that out if you’re interested in how these perform in gaming.

Bought this CPU as an upgrade from Pentium Dual Core E5200. I can say the difference in performance, response and overall use of the computer is much smoother now. I can recommend this processor as a good upgrade just right in between the Extreme Quad CPUs and the Q8xxx series. This will allow me to skip Ivy Bridge CPU generation as from the performance point of view and wait for the next gen Intel CPUs. There is also the option to overclock to push it towards the Core i5-i7 performance level without spending money on the whole platform upgrade. Mine is performing after a mild overclock on par with the Q9650 which is more expensive.
Nice and clean and well packaged and it works just great

Bought this to upgrade my q6600... noticeable performance increase. It does what I need it to, a few older games, occasional video processing.

Easy upgrade for an older pc. Installed in minutes and back up and running with a quick run through the bios.

When I built my last PC I bought and Asus moherboard with upgrade potential. Finding a used Q9550 now the prices have come down has given me a PC that loads Photoshop CS5 in 3 seconds and gives me super processing power. Well done Intel Ebay and the guy I bought a second hand Q9550 from.
