    Core 2 Duo FTW - Fantastic Value - Runs Fast & Cool

    Had some issues getting an old system running but i'm pretty sure it was motherboard related. Chip posted first attempt. I was so nervous about purchasing this cpu used, not knowing how hard it was pushed but after the past few days i'm extremely impressed. Chip arrived pretty quickly for free shipping, arrived in a small plastic tray inside a small padded envelope that seemed to keep it protected enough, but it's not overkill by any means. But I would probably ship the exact same way. I'm extremely satisfied in the performance. My cpu runs cool, low 30's idling 47-53ish under 90-100% for an hour with a decent, beefed up stock cooler that sounds like a jet. This chip is just begging to be overclocked BUT honestly I've thrown some big games at it along with a new GTX 1050 ti (which I ...

    Great CPU to upgrade an older computer.

    This CPU is great to upgrade an older computer and it performs well. I upgraded from Core2Duo E7500 to the Core2Quad Q9400 and the performance went up a lot. I put it in a Dell Optiplex 780 with a new heatsink to make it faster for a user. Just make sure you clean it and use new thermal paste and it should work well for you for basic computing or office use. I am not a gamer, but I would not expect this to work well on modern games.

    Excellent CPU for overclocking

    I managed to overclock this CPU to (stable) 3.3GHz, which is around same as intel i5 2500 base clock. This was done using stock cooler and around 1.25-1.3V. Can't remember of the top of my head accurate values. Getting non-stock cooler would probably grant even better performance. This will also work well as a mid-high range gaming PC CPU if paired with graphics card like r9 270-280 or equivalent nvidia card.

    Great upgrade for an old pc

    I had a 2 core intel cpu in a dell desktop, and came across articles where it said I could replace that with this 4 core cpu. It has worked perfectly and gave the pc some extra speed and prolonged it’s life for like $10. That’s a good deal! Shipping was very quick and well packed
