how do i know if my mother board will will handel  a Intel Core 2 Quad 2.83 GHz Processor  because i have the same 775 socket but i dont wanna buy this if i cant use it thanks

This is not an answer to this person's question, but also a question in the same regard. Have recently ordered a refurbished Opitplex GX520 and was wondering if a Core 2Duo Processor eg: E6850 would be accepted by the motherboard/BIOS. Of course it's a socket 775 chip, best guess is only Pentium 4 or Celeron is accepted. Please advise.

The Optiplex GX520 does not support any Core 2 Duo processors.

The fastest processor that's supported is the Pentium D 2.8Ghz.

Also, the following:-

Presler P4 Kit, 950, 3.4G, 2X2MB, 800FSB, C1
Prescott P4 Kit, 650, 3.4G, 800FSB, 2MB, R0
Prescott P4 Kit, 650, 3.4G, 800FSB, 2MB, Socket-T, Mainstream, N0

Prior to installing the processor, check that you have BIOS version A10, or higher installed, when support for newer processors was added.
