Its not quite as easy as that.

Firstly are we talking AGP or PCI-e? I'd think AGP with the CPU you've got, but i might be wrong.

These "HD" graphics card, ie the ATI 2x00 series only provide you with hardware acceleration when playing back HD-DVD and Blu-Ray original material through PowerDVD ONLY.

Any file based playback (expect true hd-dvd and blu-ray images) will soley use CPU power, so your 2.8ghz P4 will struggle a little. Although with the right codecs in place you 'might' just get away playing 720p wmv and h264 encodes.

See this thread for some performance stats: http://www.avforums.com/forums/showthread.php?t=666171&highlight=codec

And this for codec information:

Finally going back to the AGP questions. There are reported problems with the AGP versions of the ATI 2x00 versions of the cards where hardware acceleration doesnt work, whereas PCI-e versions work fine.

Check out this thread on avsforum for more details on the ATI 2x00 series of cards: http://www.avsforum.com/avs-vb/showthread.php?t=872538

found out from here http://reviews.cnet.com/desktops/hp-business-dx2000-pentium/4505-3118_7-30793526.html looks like i need a pci card. was thinking the Gecube HD 2400Pro, does this sound ok?

No, looking at your spec, its says your box has got a free PCI slot, not a PCI-e slot. (a very big difference!)

In terms of age, the slots go PCI, AGP and then PCI-e in order.

So looks like you need a hardware upgrade i'm afraid!! You box is pretty old!!

Going back to the card itself i'd got for a 2400XT or 2600Pro, the 2400Pro does struggle with one particular type of file, whereas the other models work flawlessly. So well worth the few extra quid.
