Pentium D to Core 2 Duo Upgrade ..... HELP!

Hi, I'm looking to upgrade my CPU but keeping the existing motherboard. Please help me out. Thanks.

Currently I have an Asus P5LD2 Deluxe board, Intel LGA 775 CPU (Pentium D 840 at 3.2 GHz), FSB at 800 MHz. The P5LD2 Deluxe board supports FSB of 1066/800/533 (according to the instruction manual).

I'm looking to buy a Core 2 Duo E7600 Wolfdale 3.06 GHz 3Mb L2 Cache LGA 775 FSB 1066 MHz.

The E7600 should be compatible with my motherboard? Am I missing any other detail? Is it "possible" to select another LGA 775 Core 2 Duo or Quad with a higher FSB of 1333 MHz instead? Any recommendations other than the E7600 CPU? If I do upgrade to a E7600, what kind of improvement will I see?

Hey,
Look inside your PC it should be printed on the Board.
If not maybe it's listed in the BIOS information
Hope this helps.

The PCB version must be mentioned on your motherboard's box cover.. Make sure you have the latest BIOS installed..

that's an old board. I would sugest to you to save you're money and do a complete upgrade. To either Core i7 or AMD. Sandy bridge will be out soon and so would be BD and bring down the price. I mean if you can swing it off becuase it would not be worth it to keep that board and LGA 775 is dead no along with LGA 1156 and 1366. Intel makes it hard to just do a CPU swap.

Thanks for the help again everyone.

Btw, my board is not a ver 2.01G :(  Yeah, it's hard to just do a CPU swap, but I tried :) 

Anyway, now I plan to do a motherboard and CPU swap instead. I plan to get the Asus P5P43TD/USB3 board and a Core 2 Duo E7600 3.06 GHz. I'll keep everything else the same (RAM, video card, etc). I'll need more help though. I'll do another post under "systems/homebuilt".

do you already have the E7600? if not go with a core i5, i7 or an AMD Phenom II or Athlon II CPU and motherboard.

Nope, I haven't purchase anything yet, just planning (to). Can you recommend an Asus motherboard for i5 or i7? Thanks.

The Asus P7P55D series constitutes some of the finest motherboards supporting LGA 1156 CPU's.. If you decide to get an i5/i7, you'd need to get new DDR3 RAM as well..

Asus LGA 1156 board $89.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16813131623

CPU dual Core i5 650 $179.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115220

CPU quad Core i5 750 $194.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115215

DDR3 4GB $66.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16820146748

This setup should last you a few years reguardless if you do go dual Core or Quad Core now let's compare prices with the E7600

E7600 $149.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115059 The core i5 or i7 performs 15% faster than the core 2 duo and quad.

just remember that the Core i5 650 and Core i7 860 has Hyper Threading enabled meaning the Core i5 650 is 2 cores and 4 threads where the i7 860 has 4 cores and 8 threads.

The Core i5 750 how ever is just 4 cores 4 threads which means HT is disabled.
