Looking for A new CPU

Greetings everyone .................

I want to buy a dual core processor with a good clock speed , FSB , and cache memory

I'm thinking about E8400 and The I5 dual core

and i want motherboard for the processor which you'll choose
it's not a matter if it's GIGABYTE or ASUS but i want it have three main features
1- USB 3.0 with a plenty of ports
2- SATA 3.0
3- more than two PCI-E slots

i have a final question
which it's better C2D processor with 3 GHz clock speed and 6 mb cache
or Core I5 with 2.66 GHz clock speed and 4 mb cache ?

More about looking
  1. Clarksdale processors, like the dual core i5 with hyper threading, can't split their PCI-E lanes to make full use of two PCI-E graphics slots. If you are interested in crossfire or SLI you will need to go with an i5 750 or go over to the AMD side. As for the Core2 Duos it doesn't make sense to build a new system around them, as they are at the end of their lifetime, unless you are on a tight budget and just really want to stick with Intel rather than use AMD.
  2. If you already have a socket 775 motherboard the E8400 will be a great upgrade i'm sure. Like mega said i wouldn't design a new system around it. The I5 is the better faster chip. The I5 even though has a lower clock speed does more per clock cycle makeing it faster then a core 2.
  3. Ok thanks for the help

    but give me a models
    and i don't quad core
    so i want I5 dual core

    what you think about this :

    Core I5-670 CPU

    GA-P55A-UD6 Gigabyte MOBO ?
  4. So you mean if i choose I5-670 i won't be able to crossfire 5770 ?
  5. if you want a dual core, id say go for a phenom II 550 BE.
  6. Tnx Guys

    but i will use the pc just for very light gaming and browsing .....

    Would I5-750 a good choice *i know it's quad* with the Gigabyte mobo that i've mentioned ?

    Avoid AMD , i know it have a great performance besides the price
    but this rig will be for my friend and he prefere Intel processors
  7. Tell your friend that he's an idiot then.

    Get the best processor you can for the job you're going to give it, and if he's only doing light gaming and browsing then he is wasting his money by insisting on Intel.

    AMD Phenom II X2 550 BE CPU
    Asus M4A785TD-M Evo motherbaord
    4GB DDR3 1333MHz RAM
    ATI Radeon 5770 GPU
    Corsair 400CX PSU
    Samsung SpinPoint F3 500GB hard drive
    SATA optical drive

    I have this system running and it's a beauty!


    If he absolutely insists on spending more money than necessary then change the CPU and motherboard to

    Intel Core i3 530 CPU
    Asus P7H55D-M EVO motherboard


    Neither of these motherboards will support multiple graphics cards, but if he's only light gaming then he has no need for Crossfire or SLI.
  8. Core I5-750
    Asus P7H57D-V EVO mobo
    Kingston KVR1333D3N9/2G 2GB*2=4GB
    XFX RADEON HD 5770
    SILVERSTONE ST56F 500W or CORSAIR HX520W or OCZ 500 StealthXstream PSU

    is it good ?
  9. There's little point getting a H57 chipset motherboard if you're not using a Clarkdale CPU, so have a look at a P55 chipset motherboard instead to see if they're any cheaper.

    The Corsair power supply is the one I'd suggest, however depending on the case you're using you may not need to get the modular HX version - the VX550 is very good quality and a bit cheaper.

    Overall it's a nice system, but honestly it's more money than he'd need to spend - even a Phenom II X4 will be cheaper and match that Intel system for performance.

    Ultimately though it's your friend's choice.

    I have a similar system to yours. My 550 is unlocked to 4 cores. I have dual 4770's and 630w PSU. Same exact MB. System flies and i cant see myself upgrading for another 3-5 years. Maybe a SSD on down the road.

    Not got round to unlocking my cores yet - need to get a better cooler first (stock cooler is fine for what I'm doing, but I didn't get a BE to keep it at stock!).
  12. Tnx for the advice :-)

    and the reason i chose H57 because he wants USB 3.0 and SATA 6 GB/S ...........

    And about the money , it's not a matter for him

    You can get that on P55 boards now too, but I think the prices work out to be the same.

    Let us know what he goes for in the end.
  14. Thanks LePhuronn

    but everything is done
  15. No , , ,

    he chose the intel rig :-)
