  1. It should fit in "1 x PCI Express x16 slot"
  2. in theory yes, the pci express slot is backwards compatible so no problems there.

    your concern though should be the extra power requirement. what's your current gpu? does it draw more or less power compared to the 7770? you know what's the model of your psu?

    my current gpu is the built-in gpu, I couldn't find my psu on the internet but it's 600W
  4. I think the 600 watts should be sufficient

    Ok,

    Well you won't know until you try. It won't break so you should go for it.

    -power off, unplug your power cord!
    -plug in the card (and additional power connector - if you have the black one on the psu - same pin number as the adapter - even better if no use the included adapter and plug 2 molex connectors to it) http://www.msi.com/pic/image/product_img/accessories_img/2008_accessories_img/powercable.jpg
    -move the monitor connector from the onboard to the new gpu
    -plug the power back on

    -pray :D

    -start up
    -in the bios you should have a options for primary vga adapter - switch it to whatever looks like pci ex(press)
    -after windows loads up install the latest catalyst driver or the one on the dvd that came with the card

    At worse i believe the system will be unstable while gaming if the psu can't give out enough juice. And if this is the case you just get a newer psu. Or go for a less powerful gpu...

    btw, i use a hd7750 on a 500w noname psu with 3 hdd-s and a power hungry phenom II black so you should be just fine
