I currently have a MS-7525 Mobo. I have a Pentium Dual Core E2160 at 1.8ghz. I have been looking for awhile to upgrade my CPU on the website with my motherboard specs it says I can use the Core 2 Duo E4xxx, and E7xxx series. But i was wondering if its possible to use the E6xxx or E8xxx series? I seem to find better deals on the 6 and 8 series. Thanks for the help.
