Graphic card compatibility

  1. Hi,

    I am new here, and had a look for this question but couldn't see it so i apologise if you've seen it before..

    I have just bought a new motherboard and processor and need a new graphics card to replace the rather slow onboard one.

    my specs so far are:
    motherboard: GeForce7050M-M
    processor : AMD Phenom 8450 Triple-Core ~2.1GHz
    memory: 2gig ddr2
    OS: Windows Xp Home

    i have been looking at the ATI Radeon HD 4870 1024MB card but am unsure about compatibility issues?
    - The spec says it takes '2 slots', does this mean 2 pci-express slots or just the space that 2 would use? Also it needs 2 pcie power connections.. Which ones are these and how do i know when my power supply is 'full' (preferably before things start melting in there..)
    - It says it uses directx 10.. does that mean you need vista to run it?
    - it uses PCIexpress 2.0. all my motherboard manual says is that it has a 'PCI Express x16 graphics card slot'

    thanks for listening, sorry if any of those questions are really stupid :)

    Two slots means that the fan is so big that the card will take up two slots, but the card will plug into a single PCI-E slot.

    DirectX 10 will only come into play if you have Vista otherwise the card will use DirectX 9.0C

    PCI express 2.0 is compatable with PCI-E 1.0. The first generation of PCI-E is so fast none of the newer video cards really need PCI-E 2. They simply are not fast enough to saturate the PCI-E 1.0 bus yet.

    Your video card will need a high powered power supply with two six pin PCI-E plugs.


    Something like this.
