Summary: For my 7-year old Dell XPS720 gaming rig, dropping a few bucks to max out the CPU with this Yorkfield and OC-it a bit and run modern games at max detail settings - you just can't beat the bang for the buck!
Summary: Really enjoying the new Quad-Core processor! Huge upgrade from my old E6600 dual core.. Also the seller did a great job of shipping it! I received it faster than expected, so I am satisfied with the purchase.
Summary: Nice upgrade from the Core 2 Duo CPU, and has extended the life of an older setup. It has served as an inexpensive upgrade that has staved off a major purchase for at least another year or two (next step would have been motherboard, cpu, and RAM, which would have cost me 4-5x what this CPU did). If you're upgrading from a Core 2 Duo cpu, do yourself a favor and upgrade to at least the stock fan of the Core 2 Quad CPU.
Summary: I thought the upgrade to Win7 64 bit with 8GB RAM would have solved some issues with my ProTools music software. But I was at the minimum requirement with the 2 cores. The upgrade to the Quad Core was the answer. I chose the Q9450 for the speed and cache. My overall PC experience has improved, although I was not dissatisfied with the E8400 either. You can't know until you try it.
Summary: This processor is a great way to upgrade a Core 2 Duo motherboard without going all in for an i5 or i7 processor. On my Windows 7 machine this processor has greatly improved performance of Adobe Photoshop CS6 and Photomatix Pro 4. That said, the stock cpu cooler is junk. I put on an aftermarket cooler and it works much better.
Summary: The processor was a good bang for the buck upgrade, now the system is maxed out on processor and ram. It's strange to see a system become more efficient with more processor cores when it comes to the electric bill, but it was! It has helped with many projects I work on and a temp solution until I can build a quality 3rd Gen i7 system with a couple of nVidia cards.
