Right now, we are at the end of the life for the socket 775 chips. the new Intel chips will be something different so unless you really need a faster CPU, id stick with what you have. If you really need more speed, id go with one of the 3+ghz core 2 duos.

Why Core2duo and not Quad?

the Duo is faster without OCing and most programs right now dont use all 4 cores of a quad

I`d go with another Quad personally. Crysis Warhead is optimised for multi-cores and it`s only a matter of time before more games are. I might do a test later so see what CPU usage occurs while playing Crysis Warhead

Also, you can run more concurrant programs quickly with the Quad - leaving an app running in the background while playing a game will have less of an impact on a quad core machine than a duo...in theory at least  8-)

   I've got one running with a QX6850, and one running with a Q9450, they both run great

Thanks all for Your input. 

 

I think I should use DarrenM343 reply, becource I have severel programs running at the same time.

 

Have a good week-end to your all.

Just a little question more

 

Will this be a good choise/replacement for my Q6600 CPU:

Intel Core 2 Quad Q9550 / 2.83 GHz ( 1333 MHz ) - LGA775 Socket - L2 12 MB ( 2 x 6MB (6MB per core par) ) - Box  -   Price in Denmark: 395$

 

Can I use Xeon in my XPS720?

    Yes, that would be a nice choice. Keep in mind, you need to update your bios to A06 before you install the chip.

 

have fun,

jd

Thx JD

 

I´m using BIOS A06 right now.

 

Is it posible to use a Xeon in a XPS720?
