Last week I bought AMD Black Edition AMD Phenom II X4 940 processor to upgrade my old one. I choose it to get more powerful performance to operate my favorite games and some design graphics activity which need high end peripherals requirement to run smoothly.
I combined this processor with my existing peripheral such PCP 790GX motherboard, 8Gb Ram and 512Mb DDR3 GeForce 9600GT PCI-X Graphic card. Since the first time I booting up using this Phenom II X4 940, I found my computer run absolutely faster when loading my Windows, more than 2 times using my old processor. When I try to run my favorite games PES2009 and NFS Carbon, I can run both games so smooth at highest detail setting. I have also try to overlock it up to 3, 4Ghz and run for a day and I found still stable performance and just a little heat which I think it is usual for any electrical peripheral to produce heat.
The price is the most reason why I choose it. It price was so cheap compare to others (especially Intel) processor equivalent. So, I recommend this product when you need to built high-end performance desktop with limited budgets.
