    the AGP bus has a higher bandwidth than the PCI bus, and so allows more data to be transferred per second, resulting in better performance and better graphics.

    If I recall correctly, the AGP bus also, unlike the PCI bus, has a direct line to the memory for texture mapping, thus avoiding the CPU and lowering resource usage. If the wiki is correct though, I may be wrong about this, or perhaps it's missing/I've missed it in the article. Not that it matters The main point is that AGP is better and faster.

    Now, PCI-E is faster again than AGP, but it doesn't appear that you have a mainboard that supports it.

    From wikipedia http://en.wikipedia.org/wiki/Accelerated_Graphics_Port (easier than looking it up in my textbooks of old.... lol)
    Again, from wiki,
    And finally, what wiki has to say aboput the speed of the PCI bus...
    http://en.wikipedia.org/wiki/PCI_bus#Conventional_PCI_bus_specifications

    Conventional, 133MB/sec peak transfer rate
    PCI 2.2, 533 MB/s peak transfer rate


    Essentiall, what's important is that AGP is far superior for graphics than PCI, unless you are considering PCI-Express.
    BTW... Intel(R) Celeron(R) CPU 2.40GHz current speed at 3200MHz - that's an impressive overclock. Did you do it yourself? :)

    Ello Spike,

    Thanks for the info :) it help a lot, as to you asking

    BTW... Intel(R) Celeron(R) CPU 2.40GHz current speed at 3200MHz - that's an impressive overclock. Did you do it yourself?

    You won't get a much faster overclock than that if you tried. I have a P4 2.26 GHZ with a NORTHWOOD core (a good core for overclocking) and mine won't go any higher that 2.72 GHZ. As for Graphics Card, from what I see on you're motherboard, you have an AGP slot. I would go with a 6600GT if you are going to do some minor to moderate gaming, 6800GS for moderate to heavy gaming, and 7800GS for extreme gaming.
