I have an old PC and i do some gaming ... ( GPU = HD7750 )
Games like Battlefield 3 and Crysis .
My board is a Asus P5K-E wifi .

I'm thinking to replace the old Cpu ( intel Core2 Duo E6550 @ 2.33GHz ) with a Xeon E5450 @ 3GHz.
I know that i have to mod the Socket by cutting the plastic ears . ( Anything else ? )
How much of improvement u thing i'll get ?

At CPU Mark rating the Core2Duo E6550 gets 1550 and the Xeon E5450 almost 2,5 times faster at 4300 .

Is it worth it ?

My other thought is instead of Xeon to get an Core2 Quad Q9550 for almost the same price 45-50$

Waiting for ur help ...

Hi, if FSB of your MOBO is OK for E5450, take E5450. You can mod BIOS of your MOBO and everything will be fine. I did it this weekend on my son´s PC, now he plays Watch Dogs. With previous core 2 Duo it was not possible.

A friend upgrade his 775 socket with intel Xeon X3380 . X3380 is for socket 775 and not for 771 like E5450 ,
His previous CPU was an E5400 core2 duo .

The difference in performance is quite noticeable , i would say big .... :D

I'm trying also for X3380 or X3370 , but there are not so easy to find.

Is it correct, that the only thing ill need to do is to upgrade the BIOS ? Can anyone tell me how ?

1) dont be confused
2) download right latest bios for your MOBO from official Asus webpage
3) mod the downloaded bios
4) download AFUWIN http://www.ami.com/Support/amibiossupport/ and flash your modded bios.

Don´t use Asus update, use AFUWIN
