I just incurred this issue, as I have a newer HP rig that uses the GeForce4 MX Series (booo!). I didn't take a look at the "No" MX Series disclaimer on the GeForce products and just assumed >< Thankfully my second PC is newly built and I loaded it with a nasty GeForce FX 5900XT card to compliment future gaming, but it still left me hangin on the first PC and needing a new card for my other copy of EQ II...since me and my wife won't start playing unless we start together.
I went ahead and ordered a Radeon 9200SE AGP card instead of breakin the bank again on another FX Series card. You can get it for $60 with shipping from www.crucial.com and it's a real decent card for the price. Lowest price I can find on a reliable FX 5200 is around 60$ without shipping, and that's relying on a no-name brand supplying it (I don't particularily like brands such as XFX and Albatron ><). If you're gonna buck up the change though, go with a higher FX series GeForce cause it runs the game like butter ^^
