I can vouch for the 4700 with integrated graphics - just installed an ATI x700pro in the pci express slot according to ChrisM's instructions in the faq - absolutely no pain and all gain.

 

As a matter of fact I think its actually easier with integrated since you don't need to do a thing except pop in the new card and install the drivers.

 

if the cash can stretch, get the 4700.

If the Dell you are planning on getting has no AGP or PCI Express slots for graphics, and you plan on using ANY form of graphics intensive software in the near or far future (i.e games etc) then do not get Integrated graphics!! i cannot stress this enough, you WILL be disapointed in the performance if you play any sort of game that has arrived within the last 2 years.

 

Hold out and get the computer these guys suggest, Integrated graphics are the bare minimum and you should avoid if you are planning on anything other than surfing and word processing.
