Hi nzrush, Welcome to THW.

To give you any type of helpfull answer we will first need to know what exact CPU you had and upraded to. Also what you use your PC for? Apps that you run? Games?

Otherwise, any answer is a shot in the dark.

Hey nzrush,

With those CPU's to put it simply you just added 2 more cores, the 200MHz difference in speed isnt going to be noticable. The only time your going to see/feel a difference between your old CPU and the new one is when your playing games that are specifically desinged to use multiple cores or in applications designed for multiple cores, like doing 3d rendering, video encoding, and file compression.

OUCH indeed :??: 
But otherwise I guess dipankar is kinda right.
For a real boost in performance, specially gaming performance, you'd need a new GPU in addition to the new CPU.
Otherwise the PC is going to be GPU limited.

hey guys, in cpu-id it comes up with my core speed being 800 mhz. Is that correct?

Are you sure you are reading that correctly? Sounds like maybe your FSB Speed but not Core Speed.

it definitely say core speed as 800mhz with the multiplier reading as 4. Sometimes it says the core speed is 2646mhz with the multiplier as 13. If im correct shouldn't the multipliers be the other way around?

No, higher multi = higher speed. It must be the power saving turning down the speed of your CPU, thats really all I can think of. But the numbers look right.
