Vista - pci express graphic compatability

I'm thinking of buying a ati radeon 2600xt 512mb pci exp DDR3 graphics card.
I have recentely bought a E'machine E4220 with DDR2 with pci express slot
and onboard graphics. Could anyone please advise.

should work with no problems just make sure you remove old drivers before
installing new card

I just bought it..and that`s why i`m browsing these forums..for me it just
dosn`t work..tried all i could..updated to latest drivers,but no luck.This
card for me takes 100% CPU all the time...when i take the card out there is
no problem at all.i was having integrated Graphics,so thought of
upgrading,but this where i`m now.But don`t worry,some users might escape
without any issues at all.i got this error while installing it:
