I replaced a Q6600 CPU with this Q9400. According to CPUBoss: "When it comes to benchmarks, the overclocked Intel Core 2 Quad Q9400 processor was able to complete the benchmark just as fast as the Intel Core i7 940 processor, which is wicked fast." But, according to UserBenchmark, the Q9400 ranks 486 out of 980 against a modern Core i9 7980XE at 1 of 980. "Considering its age it performs well in recent games'. And at a fraction ($ 13) of the cost of an i9 7980XE ($ 2.000). My (2nd) PC runs extremely well.

Trying to squeeze a little more life out of a very old computer. The CPU worked as soon as I installed it. For the price, I am very satisfied. I'm still waiting to see if I can get Windows 10 to work at a usable level.

A very easy installation into a Dell XPS420 desk top. There were no funny clitches or down loads to make it work. It was plug and play. I would recommend this upgrade.

CPU works well, I've tesed it with 100% load for a half of hour. Temperature did not exceed 40°С with a Big Typhoon cooler. I cannot try to overclock this CPU because my motherboard (Gigabyte EP45-DS3) has a problem with overclocking of any CPU. I bought a 1050TI video card, then I replaced my old Intel E8400 with this CPU, now I play Fallout 4 without any lags and hangings.

This quad-core processor is nearly the best one for the LGA775 socket which was widely used about 10 years ago and sowewhere still is. It performs roughly near the last-gen Pentium, but it can be awesome replacement for your old Core2 Duo CPU. The only issue one should take care of is its relatively big power dissipation of 95W.

This pre-owned CPU works exactly as a new one would. I had to clean it a bit before installing. The price was 7 times less than retail. Thanks a lot!

Well I assume it works, but if your thinking of upgrading an old pc keep in mind that the motherboard that support this socket tends to only super dual core CPU
