1st Time upgrading CPU, help plz.

I really just don't want to do anything stupid so I need help.

My System Specs:

Originally A Dell XPS 630i
OS - win7 Ultimate 64x
BIOS Phoenix - AwardBIOS v6.00PG
Processor - Intel E8400 @3.00GHz
Memory - 8Gb Ram
GPU - GeForce GTS 450 OC, (graphic Clock 888MHz/Processor Clock 1776)

How do I know what CPU/Motherboard is compatible? I never messed around with CPUs before.

Major Thanks in advanced to anyone who helps! :D

  1. No. You would need a new motherboard. The 8400 is, I believe a 775 socket and the I5 is an 1155...


    You can tell in the description:

    Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I52500K
  2. Thx I didn't even know what LGA 1155 stood for, So I just need a motherboard with that slot for the CPU basically?
  3. Essentially, but the cpu you linked is a "k" series which has an unlocked multiplier to allow overclocking so to go with that you would want a motherboard with a "z" series chipset to allow you to overclock. For example a Z77 chipset can be overclocked but an H77 can not.

    Also, since you will have to disconnect/reconnect everything to swap mobo's you may want to look at an overall budget/plan to upgrate gpu as well.
