Very good CPU when you mod it for LGA 775 with a sticker!

Esse processador é excelente. Da pau em vários atuais.

The Xeon X5450 is a high TDP Harpertown processor that can be fitted in many LGA 775 baords, it delivers the same perfomance as its low power counterpart, the Xeon E5450, if you're not into overcloking and if your board is compatible this CPU is a way to go thanks to its reduced price when compared to the E5450 or the Core 2 Quad Q9650. Most games will run fine but anything higher than a GTX 1050 Ti will be bottlenecked by this 10 year old chip.
