The Core I5-3570 I bought as a replacement for the i3-2120. The CPU has been detected on the first reboot by the BIOS (MSI Z68A-G43 Board (G3)) and was directly in Windows 7 (64-bit) available. Chill the system is running round (8GB DDR-3 Ram 1866er Sniper). Where it probably lies in the barely perceptible range. I have not measured it or stopped periods. I just wanted an Ivy Bridge CPU which is sustainable on my board and the 1155 base. So eventually only a new GraKa for newer games need to install and have the next year alone. Games (eg Diablo 3, World of Tanks, Risen 2) load but felt much faster.
So far I am completely satisfied and can only recommend the product.
The delivery went through Amazon.com proceeded as usual quickly and smoothly! Thanks for the good service!
