well according to my diagnostic tool i used it said that i have a PCI-E 16x slot in my machine, but the slot that you showed is not what looks like my slot! hmmmm

As you said you have a P4 I would highly doubt you have PCI-E.

More likely AGP. The brown slot and like your mobo it should be labeled, what does your say?

AGP Slot:

Usual colour coding is white is PCI, AGP is brown, PCI-E I believe can be any colour but usually white.

P4's were around at the sort of transfer of AGP to PCI-E as I have a P4 PC that has a PCI-E connector. If you still don't recognise the type of slot that it is, take a picture of all the slots, post the picture here (might need uploading to elsewhere on the net first and linking to here), then we can tell you which slots are which.

If you upload the image to photobucket then you can copy across the link it gives you.

Another possible option is to post the model number of your current GFX card.

I would imagine it is the inbuilt card Dave, otherwise I would imagine the sockets would be known. However to be sure, download GPU-Z (do a google); it's the same as CPU-Z but for your graphics card.
