Ok I just double checked the specs and you're right. That board uses the Intel integrated video. So it may just be a pci version of the 7200le. Sorry about that. My E521 is an Nvidia board custom made for dell. I slapped in an 8400GS and I'm all happy now.
But as for the poster he's going to have to go that same route. A pci version of a good Nvidia card should not be real pricey and do the job rather well.
