    I want to buy a new computer. I got a P IV 667 that really need to be changed now. I have bought a sound card (audigy) and a video card (geforce IV ti 4200) few months ago that I don't want to change right now.

    Here the first look at what I want

    Cpu: Amd 2800 or P IV 2,60 (240$ can and lower)
    Motherboard: Asus .....(depends on the cpu, need a good one but not an overpriced one)
    Hard Drive: Maxtor 120 gig 7200 RPM 8MB SATA (152,99)
    Memory: 2 x 256 DDR 400 Kingston hyper X (dual) or
    512 MB DDR 400 Kingston
    Casing: Turbo x-Alien 420 w 175$can (is that overpriced?)
    link for the case http://www.eprom.com/home/images_of_...bo/x-alien.htm

    and if I need something else, extra cooling etc just tell me

    Now the questions....



    My first question and I am sure you've seen this one really often.
    Pentium IV or Amd Athlon Xp.
    I am looking at
    Athlon xp 2800 (192,99$ can) or
    Pentium IV 478 2,40 GHz 800 FSB HT (215,99$ can)
    Pentium IV 478 2,60 GHz 800 FSB HT (235,99$can)
    Pentium IV 478 2,66 GHz 512k (219,99$can)

    For the price should I choose the Amd processor?
    And do I need that 800 bus or 512 is ok?

    Second question...
    I was looking at motherboards on ASUS website and saw that most of them got dual channel memory.
    What is this and what is better to buy?
    2 x 256 dual or 1 x 512 ddr

    Motherboards

    I like Asus and where I buy my cmputer they only have ASUS, MSI and Abit motherboards.
    Based on cpu that I said, wich ne should I take?

    Now the casing.
    I know that it is important for airflow, and to have a good power supply. But 175$ for a computer case is a lot.... ??

    Thanx a lot guys and sorry for my english

    Here is the price list of the place where Ill buy my computer
    I want to pay around 800$ or 900$. I got my sound card, video card, monitor (17 inch sony trinitron), LG cd writer, LG CD drive. Ill change the sound card, video card and monitor later this year..

    Get ya self a P4 2.4C and an ASUS P4P800 and even with the standard Intel HSF ya should exceed 3GHz (I have the same CPU but with the P4P800 Deluxe @ 3.24GHz). ;)
    The case is perfect and well worth the dollars. :thumb:
    Good luck with it.

    And for the memory?
    Wat is the difference between dual and normal?
    Is it better to have one 2 x 256 dual or one 512 normal ddr?

    Do i need any extra cooling with this case??

    Thanx

    It is MUCH better to get dual (2x256MB). The i865 chipset runs dual channel, meaning that it can use two sticks at once. So, if you have sticks, your memory bandwith is twice as much (6.4GB/s) as one stick (3.2GB/s). It is an absolute must to get dual. That case should ahve plenty of cooling, even if you're overclocking heavily. Make sure you fill all five fan slots if it doesnt come with all 5 (looks to me like it does). : peace2: Mista K6

    I think you already know that bandwidth is not linear like that...having two sticks does not give you an automatic 6.4Gb/s, that's only "theoretical".

    A 2.4c + 865PE + DDR400 2-2-2-5 will score around 4750mb/s stock.

    875P around 5k stock.

    Thought that was implied :confused: . 6400mb/s transfer would be insanely fast if it could be done, but yah, thanks for clearing that up for him soulburner :thumb: . : peace2: Mista K6

    Gentleman - especially Wiggo

    I too have a P4 2.4 C and am looking for a new mobo

    Currently have an Asus mobo with lower FSB (533)
    Looking to make the most of the 800fsb of the 2.4c an maybe clock it up a little too
    I actually have a big Zalman fan to use too

    I have read a few posts on mobos and am considering going for an Asus P4P800 Deluxe and will look at some other options

    Any other suggestions?

    I currently only have a single stick 512mb PC2700 generic ram

    Any suggestions on ram to get?
    Depending on the board i may be better served with 2 sticks for dual channel.
    I also read somewhere that pc3200 / 400mhz ram matches up better with the 800 FSB. Is this correct?

    I am also open to suggestions for (Australian) retailers.

    And if anyone wants to just give me everything I will greatfully accept!
    :laugh:
    Ok I'm dreaming now.

    Thanks all

    Get 2 sticks of 3200/3500 with fast timings (ex 2-2-2-5 is the fastest, 3-4-4-8 is the slowest), size your choice.

    The P4P800 is a great board, however for 865PE I recommend the Abit AI7 instead.

    For 875P I recommend the ASUS P4C800 Deluxe. It has PAT which is worth about 20fsb of performance, so say at 260fsb, it takes the 865P 280fsb to keep up speed wise.

    I recommend the AI7 because it can enable PAT with dividers (like 5:4) whereas the P4P800 can not.

    Man the ASUS P4C800 looks good.
    Couldnt see much diffeence between the models
    P4C800, P4C800 E, P4C800 Deluxe
    one didnt include firewire I think

    I checked prices - about $300 Australian
    which is pretty rich

    Oh well - we'll see

    other comments welcome
    Thanks Soulburner
